Typical Cross Section Description:
The R-2233BB project is new alignment approximately 5 miles long and includes two
interchanges. Typical section is four lane divided highway with 46' grass median, paved
shoulders and median ditches.
Two lane shoulder section along existing alignment that will be widened.
Annual Avg Daily Traffic (veh/hr/day):
Design/Future: 13,300 / 14,500 Year: 2020/2040
Existing: 7000 Year: 2016
General Project Narrative:
(Description of Minimization of Water
Quality Impacts)
Roadway runoff flows to grass shouders in fill sections and is collected in median and grass side ditches in cut sections to pipe systems. Pipe systems include riprap pads or
energy dissipator basins at outfalls. Two locations include dry detention ponds to reduce post construction runoff to the preconstruction discharge. Ditches include riprap lining
where sheat stress exceeds allowable for grass.
