Which Monmouth and Ocean bridges need to be fixed? These 24 are on the list
In early March, the Route 71 bridge linking Belmar and Avon stopped opening to boat traffic. The unexpected closure due to a mechanical failure adds the bridge to a list of bridges in New Jersey with poor ratings that are proposed to be monitored more frequently, rehabilitated or replaced.
Of the 749 bridges in Monmouth and Ocean counties, 59 bridges have a poor rating according to the U.S. Department of Transportation’s National Bridge Inventory. Eight out of 241 Ocean County bridges, or 3.3%, and 51 out of 508 Monmouth County bridges, or 10%, are rated poor.
According to the New Jersey Department of Transportation spokesman Steve Schapiro, every bridge in the state 20 feet or longer is inspected “at a minimum of every two years.” The average bridge age is 55 years.
“While we are making progress repairing bridges in poor condition, the condition of other bridges may worsen,” he wrote in an email.
Are modern bridges better? Baltimore's Key Bridge, opened in 1977, had few ship defenses.
“If the inspectors ever come across a structure that we determine to be unsafe, NJDOT will close either a lane or the entire bridge to make emergency repairs and would not hesitate to take the bridge out of service,” he wrote.

The NJDOT has a $85 million budget for emergency bridge repairs. In fiscal year 2024, the department’s Capital Program allocated $893 million for state and local bridges. And in 2016, the NJDOT increased its Local Bridges Fund from $25 million to $47.3 million a year. This fund allows counties to repair bridges that are under their jurisdiction.
The federal Infrastructure Investment and Jobs Acts, passed in 2021, allocated $1.14 billion in federal bridge funding money to New Jersey over five years, according to Schapiro. “So far, most of these funds have been used for project design," he wrote, "and in later years will help fund construction.”
Schapiro wrote that funding has improved over the past decade. He wrote that in 2011, 9.2%, or 605 of the 6,602 bridges then in the state were in poor condition. Currently, 5.9%, or 404 of 6,797 bridges, are in poor condition statewide.
He wrote that bridges are prioritized based of “many factors including, but not limited to, bridge condition, traffic volume, crash rates, regional needs and funding availability.”
Schapiro noted that a challenge for New Jersey is that the state has “some of the heaviest truck traffic in the nation.” He wrote that the weather with snow, ice and temperature fluctuations can cause wear and tear, especially on bridge decks.

How bridges are rated?
Bridges are rated on two scales: sufficiency ratings, rated on a scale of zero to 100, and bridge component condition ratings, rated on a scale of zero to nine per component.
According to Schapiro, for a bridge to qualify for federal bridge replacement funds, bridges must have a sufficiency rating of under 50. Federal rehabilitation funding requires that a bridge have a sufficiency rating of under 80.
Bridge components include: the deck or surface of the bridge; the superstructure, or the upper part of the bridge that absorbs the carrying weight of the bridge; the substructure, or part of the bridge between the superstructure and foundation; and the foundation or the piles in the ground that support the bridge.
If all the components are rated between seven and nine, the bridge would be considered in good condition. If the lowest-rated component is between five and eight, the bridge would be considered in fair condition. If any of the components are rated four and below, the bridge would be considered in poor condition. Components rated below a three require more frequent monitoring, load restrictions or fixes.
According to the USDOT’s Specifications for the National Bridge Inventory, the rating of four, or poor, implies widespread moderate or isolated major defects in which the performance of the component is affected; three, or serious, implies major defects in which the strength or performance of the component is seriously affects; two, or critical, implies major defects in which the component is severely compromised; one (imminent failure) and zero (failed) would require the bridge to be closed.
The National Bridge Inventory also rates the scour condition, which determines whether sediment erosion could cause the foundation to become unstable.

Of the 59 bridges in Monmouth and Ocean counties that have a poor rating, 24 bridges are currently being replaced or are under consideration for replacement or rehabilitation by the state or county. Ten bridges have recently been replaced or rehabilitated, but their status has not been updated.
Here they are:
Oceanic Bridge, also known as Bingham Avenue Bridge, in Rumson and Middletown
Lowest-rated components: Superstructure, 3 or serious, and substructure, 4 or poor
The Oceanic Bridge was built in 1939 and restructured in 1993. In 2015, a Bridge Re-evaluation and Structural Inventory and Appraisal report found that the bridge was in critical condition. The superstructure had “heavy rust throughout steel members with small corrosion holes in girder webs.” Some rivet heads, bottom flanges of the floor beams, girders, floor beams and cantilever brackets had rusting that resulted in “section loss.” And “several concrete approach spans … exhibit large spalls with exposed rebar and cracking in T-beams.” The substructure had “wide cracking and deep spalls (portions that are chipped off) with exposed and severely rusted reinforcing steel.” Its timber piles had severe decay, which required steel jackets to be installed around them. The NJDOT project is currently slated for preliminary engineering, which could recommend a plan that would replace the bridge. A project completion date has not been posted by the NJTPA.
In 2021, it had an average daily traffic of 15,030 vehicles with 4% truck traffic. In 2041, the daily traffic is expected to rise to 18,040 vehicles.
Total estimated project cost according to the NJTPA: $184.4 million.
Sea Bright Bridge in Sea Bright and Rumson
Lowest-rated components: Superstructure, 4 or poor
The Sea Bright Bridge was built in 1950 and a new bridge is currently undergoing construction next to the old bridge. The new bridge is expected to be completed by the spring of 2025. When the new bridge is completed, the old bridge will be demolished. Currently, the bridge has two lanes and an open grate section that rumbles. The new bridge will have two lanes going toward Sea Bright and one lane going toward Rumson. Its deck will be concrete, which will reduce noise and improve cyclist safety. The drawbridge will have three backups: a motor, a generator and a natural gas-powered engine.
The scour condition was rated a 3, which means that the bridge has major scour that could seriously affect the strength and stability of the bridge, according to USDOT’s Specifications for that National Bridge Inventory handbook.
In 2021, it had an average daily traffic of 11,004 vehicles with 4% truck traffic. In 2041, the daily traffic is expected to rise to 13,204 vehicles.
Construction cost according to R.E. Pierson Construction Co.: $107.5 million.
Brielle Road bridge over Glimmer Glass and Green Avenue bridge over Debbies Creek in Brielle and Manasquan
Lowest-rated components: Brielle Road, superstructure, 4 or poor; Green Avenue, substructure, 4 or poor
Brielle Road, which includes the Glimmer Glass Bridge, was built in 1889 and reconstructed in 1950. The Green Avenue bridge was built in 1946. The Glimmer Glass Bridge went under emergency repairs after it received a sufficiency rating of 2 out of 100 in 2013. After the repairs, it received a 10.1 sufficiency rating. An NJDOT project that is under preliminary engineering would rehabilitate or replace the bridges.

Total estimated project cost according to the NJTPA: $35.3 million.
Route 71 bridge over NJ Transit railroad in Deal and Ocean Township
Lowest-rated components: Substructure, 4 or poor
Built in 1917 and reconstructed in 1937, the NJDOT project would add a center left turn lane, shoulder and sidewalk. It would reduce the four lanes to two on each side and widen the bridge in anticipation of future NJ Transit lines. It would also close the intersection of Elberon Boulevard into a cul-de-sac. The project is in its design phase and is estimated to be completed in the fall 2030.
In 2022, it had an average daily traffic of 15,828 vehicles with 4% truck traffic. In 2042, the daily traffic is expected to rise to 18,994 vehicles.
Total estimated project cost according to the NJTPA: $33 million
Route 166 bridges in Toms River and South Toms River
Lowest-rated components: Bridge closest to Cedar Cove Marina, substructure, 3 or serious; bridge closest to Huddy Park, deck, superstructure and substructure, 4 or poor
Built in 1928, both bridges are in need of repair. In 2015, NJDOT closed one lane of Route 166 for emergency repairs after it found “deterioration on the underside of the bridge deck has increased at an alarming rate with concrete falling into the river,” according to a news release. Both bridges have a scour condition rated a 3, meaning major scour that affect the strength or stability of the bridge. Bridge replacement could be completed by spring 2027.
In 2020, the bridge closest to Cedar Cove Marina had an average daily traffic of 12,985 vehicles with 4% truck traffic. In 2040, the daily traffic is expected to rise to 15,860 vehicles. In 2022, the bridge closest to Huddy Park had an average daily traffic of 26,921 vehicles with 4% truck traffic. In 2040, the daily traffic is expected to rise to 32,305 vehicles.
