P1'Oj@Ct D@SC�Ipt10I1 — State project 17BP.2.R.70 involves the replacement of Beaufort County Bridge #060149
on SR 1508 (Long Ridge Rd.) over Acre Swamp. The existing bridge consists of 1@ 17' - 3", 1@ 17'-0", and 1@
18' - 0" Reinforced concrete deck spans on timber joists and is to be replaced with a 1@ 30' - 0", 1@ 40' - 0" and 1
@ 30' - 0", 21" cored slab bridge (100' total length, 33' total width) north (upstream) of the existing bridge. In
accordance with Tar-Pamlico River Buffer Regulations, the proposed bridge does not contain deck drains, all
stormwater from the bridge and approaches will be collected by a concrete flume and discharged inio a class 'B' Rip-
Rap pad within the proposed special lateral 'V' ditch al -L- 22+64 RT . Proposed ditch in the northwest quadrant is
replaced with 3:1 front and back slopes which transition to a variable width base ditch to replicate existing drainage
patterns. The proposed ditch in the northeast quadrant is replaced with 3:1 front and back slopes and ties to existing
ditches that dissipate prior to tying to Acre Swamp. Proposed ditch in the southeast quadrant is replaced with 3:1
front and back slopes and is tied to the existing ditch prior to joining Acre Swamp.
