Rte 10/Rte 322 Intersection Improvements

Fuss & O’Neill was hired to assist in the removal of an existing bridge and design of a new at-grade intersection between Routes 10 and 322.

Our engineers completed the roadway, bridge, and drainage design, utility relocation, and right-of-way acquisition. We also conducted associated hydraulic studies and environmental permitting, and will assist in the maintenance and protection of traffic during the reconstruction.

During the stage construction, 1,525 feet of Route 10 will widened from 30 to 44 feet to provide two travel lanes, a turn lane and 4 foot shoulders. The proposed Route 10 horizontal alignment will provide a 75-degree intersection, and the proposed vertical alignment has been designed to meet Route 322 at-grade.

The existing bridge was initially scheduled for replacement, but traffic studies determined that it could be removed. The proposed at-grade intersection will operate at level-of-service B or better, resulting in cost savings for the state.
