Senator Kyrillos Bridge

Red Bank, New Jersey

FPA performed a scoping study, final design and construction support services for the replacement of Monmouth County Bridge S-17, also known as Senator Kyrillos Bridge, that carries West Front Street (CR 10) over Swimming River in the Township of Middletown and Borough of Red Bank, New Jersey.

The existing bridge was a 340-foot-long, 22-foot-wide, six-span, simply supported Thru-Girder system with an open steel grid deck on pile supported concrete piers. The roadway is an arterial into Downtown Red Bank with an Average Daily Traffic (ADT) of over 20,000 vehicles at the time of the project. West Front Street (CR 10) is a one-lane roadway in each direction, curbed on both sides with sidewalks located on the north side of the road and existing bridge.

The bridge was in critical condition mainly due to advanced deterioration of the steel superstructure components. The County performed emergency repairs on the bridge, which included replacing the existing superstructure with an Acrow Panel system. The system was not intended to be a long-term solution, and the bridge was still considered to be structurally deficient, functionally obsolete and in need of replacement. FPA was retained by the County to complete technical engineering and environmental studies to move the project forward into the design and construction stages with full regulatory and public consensus. FPA also developed alternative concepts for the new configuration and recommended a final design.

The footprint of the new bridge was situated outside and to the north of the existing bridge on a curved alignment to maintain traffic on the existing bridge to the greatest extent possible during construction. A long duration roadway closure was not deemed appropriate due to predicted traffic impacts on surrounding roadways as many of the surrounding intersections were already operating above capacity. The new structure is a six-span, 488-foot-long, steel girder bridge on pile bents and pile supported abutments. Signalized intersections were upgraded along with improved roadway profile, lighting and drainage. Pedestrian activities were improved with the construction of sidewalk along both sides of the bridge, along with construction of a new walkway to cross the adjacent railroad.
