C. 211 OVER DANS CREEK CANAL State Project: 8.1430101 Federal Aid Project: BRS-7960(5) B-1140 I. SUMMARY Columbus County Bridge No. 8 has been approved by the North Carolina Board of Transportation for the Federal Aid Bridge Replacement Program. This bridge --is being replaced because of a general deteriorating condition of the substructure. The proposed bridge replacement will not induce significant foreseeable alterations in land use, planned growth, travel patterns, or in natural and cultural resources, and therefore this project will be processed as a Federal Categorical Exclusion. The existing 541-6" long structure is recommended to be replaced with a 2 @ 12-foot x 8-foot concrete box culvert on the same alignment. The recommended roadway over the culvert consists of a 20-foot wide pavement with 6-foot unsable shoulders. In using the existing alignment, minimum approach work will be required to tie the new structure into the existing roadway. During construction, traffic will be routed to a temporary CMPA culvert that is to be placed adjacent to the present structure on the west side. The estimated cost of this replacement project in 1984 dollars is $198,000. II. EXISTING INVENTORY AND HISTORY The existing Columbus County Bridge No. 8 over Dans Creek Canal is a 54'-6 long, two, lane, three span structure. The clear width of roadway on the bridge is :241-0" from curb to curb, and 25'-4" out to out of the bridge deck. Each simple span is constructed of nominal 12-inch steel stringers at 26-1/2-inches on centers that support a 5-inch concrete deck. On top of the 'concrete deck is a 1-1/2-inch asphalt wearing surface. Sub- structure construction consists of round treated timber piles, and a 25- inch deep x 24-inch wide concrete pile cap. The floor of the structure is approximately 9.0 feet above the bed of Dans Creek Canal, with a water depth at the time of the last inspection of 0.5-feet. Concrete railing is 29-inches in height above the road surface, and is continuous along the bridge length. Presently the posted load limits are 19 tons for single vehicles, and 28 tons for truck tractor semi-trailers. The present sufficiency rating for this structure is 30.3 compared to 100.0 for a new structure. The present structure was constructed in 1952. Since that time there have been no closings.or major repairs made, ';with the exception of normal maintenance such as sweeping and a new overlayment of the asphalt wearing 1 surface. The date of the last state approved condition inspection was February 28, 1984. N.C. 211 is a paved route with -an 18-foot wide asphalt surface, and 8-foot, unpaved shoulders on each side. The posted speed limit is 55 miles per: hour, and the horizontal alignment of the roadway at the bridge is 90' degrees to the flow of Dans Creek Canal. Horizontal alignment to the north and south is good, with straight roadway from each approach. Vertical alignment is good also with. flat surrounding terrain: Surrounding utilities include a telephone stream crossing 31-feet from the roadway to the east. III. ROAD,FUNCTION AND LAND USE N.C. 211 is classified as a major collector on the Federal Functional Classification System, and is on the Federal-Aid Secondary System. Principal land use in the vicinity of this bridge is primarily swamp and. woodlands. Some surrounding farmlands also exist nearby, but not in the- direct vicinity of the bridge. The Town of Bolton lies less than 3-miles to the northwest. Presently there are no USGS gaging stations near the site. Present plans for replacement include no foreseeable changes in: surrounding land use or topographic features. IV. TRAFFIC DATA AND ACCIDENT RECORDS Approximately 1300 vehicles `use this bridge daily as of 1983. It is. anticipated that by the year 2003, approximately 2300 vehicles will'use this route daily. This volume includes approximately 3% dual tired trucks, and 1% truck tractor semi-trailers daily. Since January, 1981, two accidents have been reported near the bridge. No fatalities were associated with these accidents. Two school busses use the crossing twice- daily. V. ALTERNATIVES The following five-alternatives were considered: A) No-build B) Removal of bridge without replacement C) Rehabilitation D) Removal of the bridge and replacement at the existing location E) Removal of the bridge and replacement at an alternate site ALTERNATIVE A - This alternative consists of doing nothing to the present structure, and simply leaving the bridge in its present condition. If the bridge is left as is, then deterioration that is presently takingplace in the substructure.will continue to worsen until it is in danger of collapse. 2 Maintenance and repairs required to keep the bridge open will become so numerous and expensive, it will make this alternative very undesirable. This alternative is not considered feasible. ALTERNATIVE B - This alternative consists of removing the existing bridge, and not building anew one to replace it. This alternative would eliminate the deteriorating and potentially dangerous structure that presently exists, however, it would create other problems with the present roadway system. Because of the relatively high volume of traffic that uses this roadway each day, closing of this structure and roadway would create a' detour route of over 44 miles. This would limit direct access to traffic traveling north and south across the Green Swamp from US 74-76 into Brunswick County and US 17. This alternative is not considered feasible. ALTERNATIVE C - This alternative consists of. rehabilitating the existing structure to bring it up to current design standards for loads and roadway :width. This alternative would eliminate the complete costs of building a new structure, however, the major problem with this structure lies in the supporting substructure. The existing timber piles are soft, and have deteriorated in numerous areas. The bridge wingwalls are also in a very deteriorated condition. The costs involved in making these repairs would be just as much as replacement, therefore, this. alternative is not considered feasible. ALTERNATIVE D - This alternative consists of removal of the existing bridge, and replacement with a new structure at the existing site. This new bridge would be designed to carry.-all North Carolina legal traffic loads, and would-be constructed to comply with current width requirements. During construction, traffic would be -required to either be routed to a temporary crossing, or detoured around the project site. Roadway work involved with this replacement would be minor, assuming no vertical realignment is required at the stream crossing... ALTERNATIVE E -'This alternative consists of removal of the existing bridge, and replacement with a new structure at an alternate location. This new bridge would be designed to carry all North Carolina legal traffic loads, and would be constructed to comply with current- width requirements. During construction,' traffic would, be routed across the existing structure, thus requiring no detour or temporary structure. Major costs in addition to the structure would be in roadway work, and the purchase of neW right of way. VI. HYDROGRAPHIC ANALYSIS A.preliminary hydrographic analysis was completed for this crossing. The results of this analysis are presented in the attached hydrographic analysis memorandum. 3 VII. ESTIMATED COSTS ALTERNATIVE A - No-build Not considered feasible ALTERNATIVE B - Removal of Bridge Without Replacement Not considered feasible ALTERNATIVE C - Rehabilitation Not considered feasible ALTERNATIVE D - Removal and Replacement at Existing Location Utility adjustments - Bell South = $ 8,000 Demolition & removal of existing . structure = $ 10,000 Temporary crossing (2 @ 117" x 79" CMPA) = $ 30,000 Temporary roadway = $ 60,000 Concrete box culvert = $ 34,000 Roadway approaches = $ 25,000 Contingencies and Engineering = $ 25,000 Right of way = $ 6,000 Total = $198,000 ALTERNATIVE E - Removal and-Replacement at an Alternate Site Not considered feasible e VIII. CONCLUSIONS AND RECOMMENDATIONS In examining the individual: alternatives, it is apparent that Alternative A should be eliminated because of the deteriorated condition of the present substructure. If this structure were not replaced, then major repairs would need"to be made soon to keep this bridge open t'o traffic. These repairs, in.-all likelihood, will cost as much or more than a new structure. A look at Alternative B makes it apparent that this choice should also be eliminated because of the hardships that this would bring upon the residents of the Town of Bolton and travelers across the Green Swamp. Permanent elimination of this road and bridge would- cause much difficulty for vehicles traveling north and south between US 76-74 and US 17 in Brunswick County. This closing would also create a lengthy detour for emergency vehicles. 4 Alternative C was not considered feasible because of the deteriorating condition of the bridge superstructure, and the costs in making these repairs would be more costly than replacement. Alternative E would require constructing a bridge structure on a new alignment. The present structure is on a very straight and flat section of road, and to change this alignment would produce a poorer alignment, impact the wetlands, and costs for right-of-way acquisition and roadwork would be more than for-Alternate D. Thus, this alternative is not considered feasible. Alternative D is therefore the recommended alternative. The replacement structure is recommended to be a twin 12-foot x 8-foot box culvert with a 20-foot wide pavement and 6-foot usable shoulders over the culvert. The top of the box culvert shall be approximately 1=foot below natural ground, and earth fill over the top shall be used to maintain the existing vertical and horizontal alignment. Minimum approach work shall be required to transition from the 20-foot bridge travelway to the existing 18-foot pavement. During construction this alternative will either require detouring around the site or erecting a temporary detour structure on the west side adjacent to the proposed project. If an offsite detour were used, approximately 1300 VPD would have to travel an average of 44 miles. The estimated road user costs to detour around this site would be prohibitive and at the same time impose unreasonable burdens on the public. Thus, it is recommended that a temporary detour structure made of two 117" x 79" CMPA's be constructed to the west 'of the existing bridge. The crossing will be utilized to maintain the north-south traffic across the Green Swamp during demolition and construction of the replacement project. Division concurs that this alterative is a reasonable solution. Hydrographic design shall accommodate the' 50-year flood. 1 IX. ENVIRONMENTAL EVALUATION The project is expected to have an overall positive impact. Replacement of an inadequate bridge will result in safer traffic operations. The bridge replacement will not have a significant adverse effect on the quality of the human or natural environment with the-use of current NCDOT Standards and Specifications. Therefore, the project is classified as a Categorical Exclusion.. The project is not in conflict with any plan, existing land use, or zoning regulations. No significant change in land use is expected to result from construction of the project. a ? 5 The project is rural in nature and involves only replacement of an inadequate structure at the existing location. Thus, no adverse impact on families or communities is anticipated. Right-of-way acquisition will be limited. Since the proposed project does- not increase the number of lines of traffic nor move the traffic substantially closer to the existing development, this project is not expected to alter the noise environment. The proposed bridge replacement will have no adverse effect on the ambient air quality in Columbus County. Since the anticipated traffic volume is less than 2000 vehicles per hour within a period of ten years after completion of construction, the project will be compatible with the North Carolina Plan for Implementing Natfonal Ambient Air Quality Standards. The replacement of the subject structure is not expected to result in a significant increase in traffic noise. No change in traffic patterns or substantial increase in traffic volumes will occur as a result of the project. Therefore the project is not expected to have a significant impact on existing and future land uses. Furthermore, no substantial adverse construction noise impacts can be identified. Due to the limited impact of the project and since the project has been designated a categorical exclusion, this evaluation completes the noise assessment requirements of FHPM 7-7-3 and no additional traffic noise reports are required for this project., The North Carolina Department of Cultural Resources, State Historic Preservation Officer, has conducted a review of:_ the project, and is aware of no properties of architectural, historic, or archaeological significance which would be affected by the project. They have no comment on the project as currently proposed. No wetlands are associated with the NC 211 crossing of a drainage canal, other than a few isolated pools of water. The impact of the proposed project on these wetlands will be temporary and limited to the period of construction since the replacement structure is at the existing location. Fills used in construction of the temporary on-site detour will be removed. The margins of these isolated pools and the inner slopes of the ditch support a few species of plants often found in wetlands. Some of these plant species are: black 'willow (Salix ni ra), wax myrtle (Myrica cerifera), red bay (Persia boronia), titi (Cyrilla racemifloria), elm (Ulmus ?jp.), cypress (Taxodium distichum), buttonbush Cephalanthus occidentalis), alder (Alnus.serrulata), rattan (Berchemia scandens), and rush (Jancus repens). Upland conditions in the area are of three types, a bern paralleling the ditch, slash pine (Pinus elliottii) and loblolly pine (Pinus taeda) plantation and loblolly pine woodlands with an-understory of red maple and 6 sweetgum (Liquidamber styraciflua). Few if any animal species are in the area that could be specifically associated with aquatic conditions. Fishery resources of this drainage canal are dependent upon fish movement from the Cape Fear River via Livinglston Creek. The canal is designed to carry a large volume of water during periods of heavy runoff from commercial forest lands. The canal is a tributary of Dans Creek._ Dans Creek carries a water quality classification of C SW fishing water. The ecological classification of Livingston Creek is Robin-Warmouth. No endangered' or threatened plant or animal species are known to occur at or near this bridge. The effects of siltation and erosion should be adequately controlled by the use of silt fences and other siltation and erosion control measures. It is anticipated that it will not be necessary to apply to.the Corps of Engineers for an individual.permit a's the Nationwide Section 404 permit provisions are applicable, and the provisions of Sections 330.5(b) and 330.6 of the Interim Final Rule for Regulatory Programs of the Corps will be followed. 7 a R t v tt ?

NO.: B=1140 MEMORANDUM TO: Manager Planning and Research Branch FROM: Sutton-Kennerly & Associates SUBJECT: Proposed replacement of Bridge No. 8 on N:C. 211 over Dans Creek Canal (Green Swamp)._ The drainage basin for the canal at this location is approximately 11 square miles. The existing structure consists of 3 @ 18' steel girder spans for a total length of W-6". The estimated replacement structure is s-a double 12' x 8' box culvert located so that the top is 1-foot above: natural ground and the: same horizontal alignment.as the present structure is maintained. Fill will be placed on the top of the culvert so that the grade will be the same elevation as the existing. Columbus County is a participant in the National Flood Insurance emergency program.- Attached is a copy of a section of the Bolton topographic =quadrangle (Fig. 4) on which is shown the approximate limits of the 100 year floodplain. The,floodplain in the area of.the crossing is essentially -nonexistent. A densely forested treed-farm surrounds the site. - It lot anticipated that- a permit will not= be required-to Construct a temporary crossing. If an on-site detour is required, it is recommended that 2 @ 117";x 79" CMPA's be-installed west of the present structure. A field reconnaissance will be necessary to.determine a more exact drainage area. The canal is a 20-25 foot base: box cut.. There is.no flood plain. i r - i ?IOR1H . ?IROLINN )E4?IRTMENT ? v E o i?
