Adkins Manager of Planning and Research, NCDOT 2/ySo r Date e th Bellamy 'ISivision Administrator, FHWA .t Bladen County Bridge Nos. 4 and 24 on NC 41 over Colly Creek and Colly Creek Overflow B-1051 and B-1052 Bladen County Bridge Nos. 4 and 24 (See Figure 1 for location) are included in the 1984-1993 Transportation Improvement Program as candidates for replacement under the Federal-Aid Bridge Replacement Program. Both bridges are scheduled for replacement in FY 87. The bridges are only about 500 feet apart and should be scheduled for concurrent replacement. The sufficiency rating for Bridge No. 4 is 41.2 and for Bridge No. 24 is. 45.9, compared to 100.0 fora new structure. As presented herein, the proposed replacements will not induce significant foreseeable alterations in the existing environment and therefore are considered categorical exclusions as per 23 CFR 771.115(b)(9). I. Summary of Recommendations Based on preliminary hydrologic data, the existing 35- foot structure over Colly Creek Overflow, Bridge No. 4, is recommended to be replaced on the existing alignment with a reinforced concrete box culvert, 2 @ 12 x 7. The existing 69- foot structure over Colly Creek, Bridge 24, is recommended to be replaced with a new 28-foot clear width structure approximately 100 feet long. This length may be increased or decreased as necessary to accommodate expected high flows as determined by further hydrologic studies. Minimum approach work is recommended to tie the extremities of the recommended replacements to the existing 24-foot approaches. The approximate 500-foot section between the structures should be resurfaced for continuity and safety concerns. NC 41 should be kept open during construction and traffic detoured on a temporary detour adjacent to and parallel to the existing route; the Division Engineer concurs with this recommenda- tion. The replacements should be concurrent in order to minimize disruption to traffic and take advantage of potential cost savings. The total estimated cost for the recommended replacements, in 1984 dollars, is $440,500. II. Existing Conditions Bridge Nos. 4 and 24 over Colly Creek and its overflow are located on NC 41 east of White Lake in Bladen County. In the vicinity of the existing structures, NC 41 has a 24-foot pavement width with minimum 15-foot usable shoulders. The west approach to Bridge No. 4 contains an approximate 7° 15' curve followed by a 150-foot tangent section adjacent to the structure itself. The remainder to the section under consideration is in a tangent section. The vertical alignment is good (See Figure 2). Bridge No. 4, the most western of the two bridges, is a reinforced concrete and creosote timber structure approximately 35 feet in length. Clear roadway width on the structure is 24 feet. The posted weight limit on the structure is 21 tons for SU and 26 tons for TTST. The paved surface across the structure is in fair condition. Bridge No. 24, over Colly Creek proper, is also a reinforced concrete and creosote timber structure approximately 69 feet in length. Clear roadway width on this structure is also 24 feet. The posted weight limit on the structure is 19 tons for SU and 23 tons for TTST. The structure is in fair condition, exhibiting deterioration in the timber piles. The paved surface across the structure is in fair condition. NC 41 is a rural major collector route currently carrying approximately 1400 vehicles per day (VPD). The traffic volume is anticipated to increase to.2400 VPD by the year 2004. It is estimated that 4 percent of this volume consists of dual-tired vehicles and 2 percent truck-tractor semitrailers. There have been no reported accidents attri- butable to the structures or approach alignment since January, 1980. Normally, 14 regular school bus trips per day utilize these crossings. Land use in the project vicinity is principally wooded. swampland and farmland. Some residential development exists at both ends of the project. Utilizing the temporary detour as shown in Figure 3, it is not anticipated that these properties will experience any adverse affect. Utility lines parallel the south side of NC 41. It is expected that the utility line will be relocated or adjusted as a result of the project. III. Alternatives, Costs and Recommendations Due to the adequate horizontal and vertical alignment available at the existing site and the availability of a potential off-site detour, the existing alignment was the only replacement alignment considered (See Figures 1 and 2). A no-build alternative was not considered due to the deteriorated structural condition of Bridges 4 and 24. A rehabilitation alternative is also impractical. The existing substructure, namely the timber piles, of both structures are cited as having varying degrees of softness and decay. To replace the substructures of the bridges would nearly equate to totally reconstructed structures. 3 Two replacement alternatives were analyzed. Alternate 1 consists of replacing the structures in their existing locations and utilizing an on-site temporary detour (35 mph design speed) paralleling the southside of NC 41 and lying between the existing pavement edge and woodsline. At Bridge No. 4, the temporary detour structure would be a single 60- inch CM pipe; and at Bridge No. 24, 5 @ 72-inches- CM pipe. Alternate 2 consists of replacing the structures in their existing locations and utilizing an off-site detour-- US 701 and SR 1514. Through traffic, there is little development along NC 41 between US 701 and SR 1514, would have to travel approximately 7.5 excess miles. During the course of one year's construction time, the additional road user cost incurred by the public would be approximately $960,000. For through traffic between White Lake and Sampson County an additional off-site detour exists--US 701 and NC 210. Through traffic on this route is estimated to be approximately 800 VPD. With 4.8 excess miles of travel and one year's construction time, the additional road user cost incurred would be approximately $350,000. The estimated costs for the construction alternates, in 1984 dollars, are given below: Alternate 1 Alternate 2 Bridge No. 4 Approaches $ 13,000 $ 14,000 Structure (RCBC, 2 @ 12 x 7) 38,000 38,000 Structure Removal 3,000 3,000 Bridge No. 24 Approaches $ 31,000 $ 35,000 Structure (28-foot clear width) 131,000 131,000 Structure Removal 5,000 5,000 Temporary Detour $157,000 NA Engineering and Contingencies $ 57,000 $ 34,000 Right of Way 5,500 3,250 Total $440,500 $266,250 Alternate 1, utilizing an on-site temporary detour, is recommended for the following reasons: (1) the temporary detour provides the traveling public a minimum "benefit-cost ratio" of approximately 2.2 compared to using an off-site detour; (2) considering the excess road user cost, Alternate 1 is less expensive and; (3) the environment and existing 4 development are not materially compromised by the temporary detour. The Division Engineer concurs with this recommendation. IV.. Environmental Evaluation A biological evaluation of the sites for the above referenced projects was conducted on September 28, 1984. Because of the close proximity of the two bridges to each other, (approximately 500 feet apart) community structure and composition was identical at both locations. Project plans call for both bridges to be replaced in existing locations with temporary structures to be positioned adjacent to, and south (downstream) of, the current bridges to accomodate local traffic during construction. With the exception of the two private residences east of Bridge No. 24 (one on each side of the highway), land in the project vicinity consists of a blackwater swamp hardwood forest classified as Palustrine Forested Wetland by the U. S. Fish and Wildlife Service. These communities are subjected to regular flooding and function as outstanding wildlife areas. Vegetational coverage is prolific and dominated by such species as bald cypress (Taxodium distichum), red maple Acer rubrum), black gum N ssa sylvatica var biflora), red bay Persea borbonia), sweet gum (Liquidambar styraciflua), black willow Salix nigra), sweet bay (Magnolia virginiana) and others. American holly Ilex opaca), red titi (Cyrilla racemiflora), pepperbush (Clethra alnifolia), dog laurel (Leucothoe axillaris), cane (Arundinaria gigantea) and brier Smilax sp?p) are common in the understory. Spanish moss (Tillandsia usneoides) is an ephiphyte frequently sighted throughout the canopy layer. Maintained right-of-way margins bordering NC 41 vary in width from approximately 20 feet along the northern flank to about 40 feet just south of the highway. This southern corridor also allows for maintaining the utility line providing service through this area. These transitional communities support a variety of low growing, successional species including ragweed (Ambrosia spp), painted leaf (Euphorbia heterophyl-la), Florida pusley (Richardia scabra) blackberry Rubus pp), dog fennel (Eupatorium capillifolium), honeysuckle (Lonicera sip) and grasses. Wax myrtle M rica cerifera) is common along the woodland fringe. Meadow beauty Rhexia virginica) proliferates around creek margins. Animal life expected in the project vicinity includes opossums, swamp rabbits, raccoons, river otters, skunks and others. A variety of reptiles and amphibians such as turtles, frogs, snakes, salamanders, etc are common to these communities. Because of the extensive nature of swamp development associated with Colly Creek, black bear Ursus e 5 americanus) and alligators (Alligator mississippiensis) are suspect. These forested areas potentially provide habitat for a variety of avifauna including warblers, hawks, flycatchers, wrens and similar species. Egrets and herons are known to nest in cypress trees such as those found in this region. Colly Creek and its tributaries flow in a southerly direction through the project area. This blackwater swamp system has been given a sanitary classification of C Sw by the N. C. Division of Environmental Management indicating suitability for fishing, fish propagation or other uses requiring waters of lower quality. The watercourse has a Redfin-Warmouth ecological classification providing recreational fishing opportunities for redfin pickerel, catfish and various sunfishes. The dense undergrowth generally limits fishing to bridges and road crossings. - The proposed project will involve replacement of both bridge structures in their existing locations. Adjacent, temporary facilities will be provided to accomodate continous traffic flow during the construction period. A southern (downstream) alignment is being considered for the detour structures. This approach is preferred from an environmental standpoint since most activities can be concentrated within disturbed right-of-way margins with limited need for additional canopy removal. Some minor fill will be required in adjacent wetlands to accomodate temporary bridge approaches. Removal of detour fill and structures is recommended after project completion as mitigation for temporary loss of wetland habitat. Strict erosion control measures should be required of the contractor to reduce sediment input into creek tributaries and wetlands during construction. Such measures as silt curtains, berms, silt basins and others as outlined in the State approved Erosion and Sedimentation Control Program will help to reduce likely adverse impacts on aquatic communities. No rare or endangered species are expected to be impacted by this project. Although American alligator, a species classified as endangered, may be found in the general vicinity because of their habitat preference, the limited scope of this particular bridge replacement activity precludes infringement on their well being. Colly Creek in Bladen and Pender Counties is listed in the Nationwide Inventory of Rivers as one with potential for inclusion in the Nationwide Inventory of Rivers as Scenic Rivers System. The narrative description of values states, "Remote float stream that flows through Bladen State Forest." Potential significant adverse effects on the natural, cultural and recreational values of this river by the 6 Y, proposed project include unavoidable temporary deterioration of water quality resulting from erosion and siltation due to construction activities and alteration of the setting due to replacement of existing structures with new, modern crossings. These effects would not foreclose options to designate the river under the Wild and Scenic Rivers Act. Therefore, no special precautions are necessary to avoid or mitigate these effects other than stringent erosion control measures to be employed during project construction. No permits will be necessary for construction of the project. It will not be necessary to apply to the Corps of Engineers for an individual permit as 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. The recommendation is to replace the existing structure at the same location. Therefore, the subject project is exempt from the Farmland Protection Policy Act. Since the anticipated peak hourly traffic volume is less than 2000 within a period of ten years after completion of construction, the project will be compatible with the North Carolina Plan for Implementing National Ambient Air Quality Standards and will not have a significant impact on air quality. The replacement of the subject structure is not expected to result in a significant increase in traffic noise. No change in traffic patterns or 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 significant adverse construction noise impacts can be identified. Due to the limited impact of the project and since the project has been designated a categori- cal 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 State Historic Preservation office will be given an opportunity to review this document and make their recommendations as to whether an archaeological survey will be needed. No structures of historical significance will be affected by the project.
