Byron Highway Bridge Replacement, Project No. 4660-6X104B, CP# 19-36

The Project will replace the existing bridge with a multi-span concrete bridge approximately 360 feet long, and a clear width of approximately 40 feet. The Project would also make approximately 1,350 total feet of roadway improvements on either side of the new structure. The proposed road and bridge would realign Byron Highway slightly to the south. In its final. configuration, the replacement bridge would accommodate two lanes of vehicular traffic (one in each direction) with no increase in capacity. The proposed bridge would have eight-foot wide shoulders on both sides of the road. The eight-foot shoulders would meet American Association of State Highway and Transportation Officials (AASHTO) minimums and would be consistent with the countywide Bicycle and Pedestrian Plan that would accommodate a Class 2 facility with buffer striping at the Project site. The work also includes modified connections for four access. roads near the ends of the bridge and modification of the Bruns Road intersection. Extensions of existing culverts and modifications to other drainage features such as ditches and swales would also be performed. Utility relocations and right of way transactions will be necessary.
