Work is expected to last 270 calendar days, weather permitting. The bridge is located between Stobbe Lane and Sunnydale Way.

The road is expected to be closed to through traffic for the duration of the project. Marbro Inc. of Montclair will perform the work. It was the successful low bidder at $3,547,117. The contract was awarded on Aug. 10.

The existing bridge carrying Cranbury Road over Bear Brook is a four-span, simply supported, pre-stressed voided slab beams supported on steel piles. It is in poor condition due to substructure defects. It was categorized as structurally deficient with a sufficiency rating of less than 50 percent.

The replacement bridge will be a two-span structure supported on full height abutments and hammerhead pier. The proposed cross section at the bridge will consist of two 12-foot travel lanes, two 6-foot shoulders and two 6-foot sidewalks and four-rail bridge railing.

The superstructure will consist of curved steel beams with a reinforced concrete deck composite section. The substructures will be founded on pile foundations with permanent scour sheeting.
