 route 70 bridge over manasquan river - september 11 memorial bridge

Project Description

The Route 70 project has been designed to address both structural and functional deficiencies of the existing bridge crossing and provide for the long-term regional transportation needs along the Route 70 corridor and the Manasquan River. The design will carry the dualized section of Route 70 across the Manasquan River and complete the infrastructure improvements from Jack Martin Boulevard to the Brielle Circle. The bridge will have a 12-foot median, two 12-foot lanes and one 10-foot shoulder in each direction. Sidewalks and parapets are included on each side of the bridge resulting in an overall bridge width of 94' 8".
