Project Description

The project will improve traffic flow, capacity, and safety for motorists, pedestrians, and bicyclists by widening the roadway from three to five lanes. It will include two through lanes in each direction with a center two way turn lane continuous curb and gutter raised bike lane (providing a physical separation) and sidewalks on both sides with ADA compliant curb ramps at all designated crossing. This will align with the five-lane road configuration to the north and south thus eliminating the bottle neck in this section of the corridor. The traffic signal upgrades and improvements to the intersection at the SR 525 NB On/Off Ramps will increase capacity and improve travel times at this intersection. Storm water conveyance and water quality treatment facilities will be developed as part of this project. Three fish bearing culverts will be upgraded to Box culverts to meet the current standards to ensure fish passage.Low impact illumination will be installed throughout the corridor.
