P.I. 0010425 is the grade separation of Walther Boulevard over SR 316 in Gwinnett County that is partially located in the City of Lawrenceville. The proposed project is approximately 0.3 miles in length and consists of a four span bridge 404 feet in length. The bridge span and arrangement do not preclude the addition of a High Occupancy Vehicle (HOY)/Managed Lane access point as well as the subsequent required widening of SR 316. Walther Boulevard would consist of two12-foot travel lanes, a 14-foot two-way left turn lane and 16-foot shoulders consisting of a five foot pedestrian sidewalk. Proposed project 0010425, Walther Boulevard at SR 316 grade separation, was originally evaluated in an Environmental Assessment (EA)/Finding of No Significant Impact (FONSl) as part of PI 0003168 and along with PI 0004086. PI 0003168 is the addition of HOY lanes along SR 316 from roughly 1-85 to Cedars Road (a distance of 8.8 miles). PI 0004086 is the grade separation and operational improvements to Collins Hill Road and SR 20. PI 0004086 is currently under construction. PI 0003168 is unfunded (Lrl). The proposed grade separation at Walther Boulevard/SR 316 (PI 001 0425) has been programmed for Fiscal Year (FY) 2014 Right-of-way (ROW). Although the proposed improvements were originally evaluated as part of 0003168, the grade separation of Walther Boulevard at SR 316 is an independent project from the construction of the SR 316 HOY lanes. Therefore, this investigation will only provide updated information for the area affected by PI0010425.
