Project Spotlight: Final Design of Monmouth County Bridge S-17 Over the Swimming River

FPA was retained by Monmouth County to advance the scoping documents prepared by this office through final design for Monmouth County Bridge S-17. The multi-span, 340-foot long bridge carries West Front Street (C.R. 10) over Swimming River from Middletown into downtown Red Bank was determined to be structurally deficient and functionally obsolete. The final design was completed in compliance with FHWA NEPA guidelines as a Categorical Exclusion.  The project included a comprehensive community outreach effort, and development of design plans based on the approved preferred alternative and obtained Environmental approvals from NJDEP and the US Coast Guard as well as the NJDOT and FHWA. The final design involved the preparation of construction documents for a new bridge on adjacent parallel alignments in an effort to maintain traffic during construction; minimize impact to the surrounding towns during the summer seasons months and maintain the navigable waterway associated with the bridge.  Critical project constraints included tidal wetland impacts, wetland mitigations, obtaining regulatory approvals, bridge aesthetics consistent with the historic nature of the adjacent community, and maintenance of traffic. The new 488-foot long steel girder bridge consist of six (6) 80-foot spans supported on pile bents and pile supported abutments.  Each span was 55 feet long between bearings.  Two signalized intersections were also upgraded along with improvements to the roadway profile, lighting and drainage through the limits of the project.  Pedestrian activities were improved with the construction of sidewalk along both sides of the bridge and upgrades to all handicapped ramps to be compliant with current ADA requirements.
