Monmouth County has been investigating the replacement of the Oceanic Bridge for almost 20 years
Now, Monmouth County officials have released details about plans to replace the 86-year-old drawbridge that carries Bingham Avenue across the Navesink River between Rumson and Middletown.
The new span would rise 65 feet at its highest point, high enough for boats to pass underneath, so it would no longer need to open. It would also add a wide path for pedestrians and cyclists.

The current bridge is rated in poor condition, with heavy rust and holes in parts of its superstructure, according to engineering documents. Its last major rebuild was in 1970.
As the drawbridge has deteriorated, the weight limit it can support has been lowered. That means it’s off-limits to vehicles heavier than the current 15-ton weight limit. That affects use of some fire trucks, since the average pumper ranges between 15 to 30 tons.
The metal drawbridge has also had its share of mechanical problems, including being stuck in the open position, which is usually due to extreme summer heat. But in June 2015, problems with the movable part of the bridge forced crews to leave the bridge in the open position to make repairs.
This year, on July 1, the opposite problem happened: the Oceanic Bridge was stuck in the closed position, according to the U.S. Coast Guard.
“It’s an important connection,” said Monmouth County Commission Director Thomas Arnone. “It’s fully funded with federal dollars, but there are steps that have to be done.”
To qualify for federal funding, the project must go through four phases of design work and environmental studies. Monmouth County and the North Jersey Transportation Planning Authority are in the second phase, which is expected to take two years. Cost estimates won’t be known until the final design phase, according to county documents.
The design of the replacement bridge bears some resemblance to the Route 36 Highland bridge serving Sandy Hook, which replaced an old drawbridge with a 65-foot span, eliminating the need for the bridge to open for boats.
Unlike the Highlands bridge, the Oceanic Bridge concept design calls for a gentler grade. Renderings show a less steep profile that makes the bridge usable by pedestrians and cyclists.
While the project is federally funded, cost estimates won’t be known until after the final design phase, according to county documents.
While preliminary engineering and design work is being done, some design decisions have been made, including building two roundabouts where the bridge ends in Middletown.
The first roundabout would replace the current intersection at Navesink River Road in Middletown.
One roundabout on the Middletown side would lead to a planned 20-foot-long promenade on the banks of the river. The other would replace the conventional intersection at Navesink River and Locust Point Roads, which is now controlled by a traffic signal and is expected to reduce crashes.
On the Rumson side, three options are being considered to connect the bike and pedestrian path to Victory Park. None are roundabouts.
Options include paths 8, 10 or 14 feet wide that either end at Hunt Street or River Road.
Another concept would replace the two existing sidewalks with a 14-foot-wide shared, protected bike and pedestrian path on the west side of the new span. The new bridge would have two 11-foot-wide travel lanes and two eight-foot-wide shoulders.
Pedestrian overlooks are being proposed, similar to those used at the Scudder Falls bridge in Mercer County and the Route 52 Causeway in Cape May.
A tentative schedule calls for the Local Preliminary Engineering (LPE) phase to be completed in fall 2027, followed by final design work that is anticipated to start in spring 2028.
The beginning of construction depends on when final designs are completed. Officials estimate that construction is at least four years away, and that depends on design review and on obtaining nine required permits. These phases are necessary to qualify for federal funding, officials said.
The next public meeting is anticipated for summer or fall 2027 to review the environmental assessment. Updates, comments and questions will be available on the project website.
A first meeting was held on Sept. 29 to present the project.
