Traffic on National Road in the AM and PM peak periods caused queuing adjacent to the signalized intersections.
LJB’s design included a 400′ long northbound right turn lane on Grange Hall Road to Colonel Glenn Highway, extending the second northbound thru lane on National Road north of Colonel Glenn Highway, moving the signal pole at the southwest corner of the Colonel Glenn Highway intersection to install the right turn lane, extending the sidewalk on the east side of National Road, and milling and resurfacing of the entire length of the project, as well as installing curb, gutter and storm sewer.
A maintenance of traffic scheme that included closure and detour of one direction of traffic was implemented to limit costly temporary pavement and permanent right-of-way needs.
The typical section for this improvement was studied to minimize any reconstruction with a future phase of improvements to Grange Hall and National Roads.
Because of the corridor’s close proximity to WPAFB, LJB’s design was careful to avoid their perimeter fence while also navigating the process by which an easement from the base could be secured for the roadway widening required.
