MORRIS COUNTY, NJ – The Palmer Road Bridge over Mill Brook, located in the townships of Denville and Randolph, is now closed for replacement construction that began Monday and will continue for eight months.
Built in 1917, the bridge is a single span steel beam structure. It has an average daily traffic of 5,400 vehicles and is in poor condition due to the deterioration of structural steel beams, which prompted the replacement project.
Construction has begun, and the road is closed to all traffic. Motorists are being detoured onto Franklin Road, Route 10 and South Salem Street while construction is underway.
The overall structure length is 26 feet and the deck width is 34.6 feet. The proposed bridge replacement will consist of a precast concrete, three-sided rigid frame on cast-in-place concrete foundations. A painted four-bar steel railing will be placed across the structure between the stone-faced pylons.
The guide rail along the approach roadway will be stained with a brown finish to aid in blending the structure into the surrounding area.
The contractor on this project is CMS Construction of Plainfield, N.J. The estimated project cost of $1.1 million will be funded by both the state and county.
