The project includes upgrading the existing Route 34/51 intersection to improve turning movements for tractor trailers and other larger vehicles. This will be accomplished by widening and increasing some of the radiuses at the existing intersection. The project also includes improvements to the pedestrian crossings and adding a section of sidewalk to connect to the existing pedestrian facility.
