R-2514B is the planned new US 17 bypass of Maysville. Two major structures are planned at the crossing of the L Line (US 17 Bypass) with Higgins Branch and the White
General Project Narrative:
Oak River. The structure over Higgins Branch is 2@80' 45" Girders for a total length of 160', while the structure over White Oak River is 2@100', 7@110', 1@100', and1@90'
63" MBT for a total length of 1160'. Grass lined ditches are utilized throughout where possible. Any ditches draining to wetlands were daylighted 10' before entering the
wetlands to prevent concentrated flow from entering and additional impacts to the wetlands. Rip Rap toe protection was used in areas where this was not possible to maintain
non-erosive velocities through the wetlands. 36" RCP-IV Equalizer Pipes were used in areas where the proposed roadway is splitting wetlands: STA. 72+04 -L-, 75+50 -L-,
151+92.61 -L-, 157+27.35 -L- to allow for water to pass freely from one side of the highway to the other allowing for wetlands to remain viable. Storm drain outfalls have been
located outside of wetlands where possible.
