NJDOT’s Route 71 Shark River Bridge Preservation and Road Diet project has been selected as a regional winner in the 2023 America’s Transportation Awards Competition. The competition is sponsored by the American Association of State Highway and Transportation Officials (AASHTO), AAA, and the U.S. Chamber of Commerce.
The Route 71 Shark River Bridge Preservation and Road Diet project received honors in the Operations Excellence, Small category. This year’s regional winners were chosen from a selection of 19 projects nominated by nine states in the Northeast Association of State Transportation Officials (NASTO) region. The NASTO region’s winners will compete for the National Grand Prize, the People’s Choice Award, and $10,000 in cash awards that will be given by the winners to a transportation-related charity or scholarship program of their choosing.
After the Route 71 Drawbridge over Shark River between Belmar and Avon-by-the-Sea in Monmouth County suffered a mechanical failure in September 2021, engineers devised a cost-effective design and implementation solution that would preserve the drawbridge and keep it in safe operation.
NJDOT implemented a road diet across the bridge, which allowed the Department to address safety issues. Traffic over the bridge was reduced from one northbound lane and two southbound lanes to one lane in each direction.
With the lane configuration reduced to one lane in each direction, NJDOT was able to extend bicycle lanes that previously terminated in Avon-By-The-Sea across the drawbridge into Belmar. Previously, bicyclists needed to dismount and walk their bicycle across the bridge. The extended bicycle lanes were accomplished using an innovative fiber-reinforced-polymer mat on the bascule span. The mat is the first of its kind in New Jersey and provides a safe crossing of a steel-grid deck for bicycles. The extended bicycle lanes provide connectivity between both downtown areas and area heavily utilized by bicycle traffic year-round.
Safety improvements to the Rt 71 over Shark River Drawbridge Included a bicycle safe grid on the draw span which allows bicyclists to cross without the need to dismount.
NJDOT was able to improve traffic flow at the Fifth Avenue intersection with the road diet project. Previously, two southbound lanes crossing the drawbridge on Route 71 were a source of traffic backups with left turning vehicles occupying the left lane, compounded by an abrupt merge south of Fifth Avenue. The merge that previously existed on Route 71 south of Fifth Avenue in downtown Belmar was eliminated with the road diet project. The road diet configuration retained one through lane southbound and installed a dedicated left turn lane at the Fifth Avenue intersection. Signal timings were changed, and a protected left turn phase added to further improve traffic flow. Careful monitoring of traffic throughout the year, and especially during bridge openings, have shown that the road diet lane configuration greatly improved traffic flow.
The Route 71 Drawbridge Project over Shark River, completed in May 2022, delivered several benefits, including improved traffic flow, reductions in traffic congestion, increased safety and an enhanced cycling experience for users navigating a busy shore community tourism area.
Road Diets are a safety-focused alternative to four-lane, undivided roadways that can help reduce vehicle speeds and free space for alternative transportation modes. Road Diets were a recognized model innovation during the 3rd Round of the Every Day Counts Program (EDC-3) Program.
Additional information about the rationale, design and benefits of advancing this innovative bridge safety and road diet project can be found in the video here and in this NJDOT press release.

NJDOT, like other State departments of transportation (DOTs), has become increasingly conscious of infrastructure’s environmental burdens and are seeking more environmentally sustainable materials in construction. Recently, we spoke with Kimberly Sharp, Manager, Structural Design, Geotechnical Engineering and Geology, and Mohab Hussein, Project Engineer, Deputy Chief Technical, Geotechnical Engineering about NJDOT’s adoption of Foamed Glass Aggregate which serves an example of the deployment of an innovative, sustainable material.
To make foamed glass aggregate, crushed container glass is collected from recycling companies, finely ground into powder and mixed with a foaming agent, and sent through a kiln and softened. Bubbles form within the softened glass. When it cools, the material cracks and forms lightweight, coarse, foam-like aggregate pieces that can be used in various transportation construction projects.
Q. How did you learn of this material?

Aero Aggregates in Eddystone, Pennsylvania, reached out to the Department in 2018 to provide a technical presentation on foamed glass aggregate. An industry presentation is an established step in NJDOT’s process for exploring new technologies. If we are interested in the product, as we were in foamed glass aggregate, we start a pilot project.
Q. When did NJDOT begin using foam glass aggregate?
Our pilot project was the Rt. 7 Wittpenn Bridge in Kearny, NJ in 2019. Use of this material replaced 32,000 cu.yds. of regular fill and saved almost 28 million bottles from the landfill. We used the material for a crossover from one side of the road to the other. We built it and let the contractor use the area for six weeks with heavy equipment traveling over it. We maintained survey equipment at the site and looked for settlement and any lateral spreading and nothing moved.
Q. What have been the most common uses?
For us at NJDOT, the most common uses have been as fill underneath roadways to raise the profile, behind existing abutments where we were putting in a new backwall and new girders and we wanted to lighten the lateral forces on the backwall, as backfill to the approach to a bridge, to resolve sheeting issues on a project, and as backfill behind a temporary wire wall.

We have very soft, compressible soils beneath some of our roadways, and in areas of high tide or frequent flooding, therefore we want to raise the elevation of the roadway. Using heavy, natural fill material beneath the pavement box can lead to pavement that ultimately would ride like a roller coaster due to uneven settling. A less costly approach is to over-excavate the existing soil and place with the foamed glass aggregate. At 22 lbs./cu.ft., the aggregate is buoyant, so regular weight soil is placed over it to weigh it down, and then the pavement box is built on top of the soil. Use of the aggregate lessens the amount of settlement and results in a nice smooth roadway.
Q. Who are suppliers of this material?
Aero Aggregates is the supplier that we work with. They recycle glass from Pennsylvania and from a southern New Jersey recycling center. We appreciate that they are using local materials.
Q. What are the environmental benefits of using this material? What is it replacing?
Foamed glass aggregate is saving millions of bottles from landfills. This material is made of 100 percent recycled material. In addition, the material replaces traditional backfill that would be quarried, and so minimizes depletion of natural resources. It also minimizes use of other material such as rebar, concrete and other foundation elements. In addition, it is lightweight, about half the weight of regular lightweight fill material, and so reduces transportation emissions. There are associated cost savings to its use.

Q. Is there an ongoing assessment process for use of this material, or is it an established process?
We had questions in the beginning. The material was so light that we worried about its durability. The manufacturer provided results from testing and we tested the material in the field. Use of foamed glass aggregate is an established process at NJDOT. The material was first used in Germany in the 1980s, and in Norway in the 1990s to prevent rutting of pavements because it has good insulating qualities. It is useful in cold regions.
Q. Are there limits to the transportation construction applications where this material can be used?
Foamed glass aggregate has its own compaction requirements; it is lightly compacted or graded out with lightweight equipment to avoid crushing of the aggregate. As mentioned above, it requires capping to weigh it down. Pavement design engineers want several inches of regular weight soil between the lightweight aggregate and the pavement box.
Q. What is the state of industry knowledge and acceptance of the use of this material?
It is still early in the process of nationwide adoption. New Jersey is one of the first states to implement use of the material on our projects. We have received calls from many state DOTs asking how we began using it, and about our experience of using it in lieu of other lightweight material, so word is getting around. Aero Aggregates used it in Philadelphia around I-95. The industry is working on starting up new plants. Word is spreading through the contracting community. The first contractor that used it with us liked it so much they eliminated all other lightweight types of materials in the contract bid items. Through word of mouth, other design consultants and Contractors have picked up on use of the material.
Q. Do you have current projects where this is being used and do you anticipate continued use of the material in the future?
View video on YouTube or access it from the NJDOT Platform
Yes, and we have some in design, and we will include foamed glass aggregate in the contract for future projects for consideration.
For future projects, we have not used foamed glass aggregate behind structural walls as yet, although we know it has been used in Philadelphia, and we are considering that application.
The Department is also considering applications related to temporary water storage in flood areas. Our current and past projects are using closed cell foamed glass aggregate, but an open cell aggregate is available. Its porosity might be beneficial in flood mitigation and other resiliency projects.
We really like the product and look forward to expanding its use. We are always looking for new technologies and this is one that will continue to be of great benefit.
Q. What do you consider to be the keys to the successful adoption of the material?
Agency willingness has been the key to successful adoption of this innovative material.
The American Association of State Highway and Transportation Officials (AASHTO) Innovative Initiative (AII) program recognized NJDOT’s Sawcut Vertical Curb as one of seven Focus Technologies in 2022. AASHTO held a webinar on Wednesday, April 12, 2023 during which NJDOT practitioners and contractors offered their first-hand experience with implementing the saw-cutting method on their projects successfully. The innovation was also recognized as the NJ’s Build a Better Mousetrap Winner in 2022 and a video description of the innovation can be found here.
Below is a reprint of the AASHTO Innovation Initiative Page that features the Saw Cut Vertical Curb and can be accessed here.
NJDOT’s Saw Cut Vertical Curb is featured as an AASHTO Innovation Initiative.
The AASHTO Manual for Assessing Safety Hardware (MASH) establishes uniform standards for the installation of roadway safety features, including longitudinal barriers. In accordance with the recent MASH standards, the New Jersey Department of Transportation (NJDOT) has updated the installation requirements for guide rails. Per this new requirement, curbs in front of and along guide rail end terminal treatments should be limited to a maximum 2-inch exposure. The typical exposure of existing curbs is four inches. To make guide rail installation MASH compliant, the conventional practice is to remove existing curbs and replace them with 2-inch curbs. The practice typically requires seven days of field operations for the removal, replacement, and curing of concrete. Not only does this timeframe add to labor costs, but also exposes work crews and motorists to work zone traffic for longer periods of time.
NJDOT has developed an innovative method in which the existing curbs can be saw cut to two inches in lieu of removal and replacement. The existing guide rail can remain in place during saw-cutting, while the construction crew can return at a later time to remove and upgrade the guide rail. The saw-cutting approach requires only two days of labor. The process uses a power-driven vertical curb saw fitted with horizontally-oriented, diamond-edge blades or abrasive wheels that are capable of sawing to the required dimensions without causing uncontrolled cracking. The saw is water-cooled, circular, and has alignment guides. The saw is also capable of immediately collecting the slurry produced from cutting the concrete. Traffic control in work areas requires a moving operation set up that includes channelizer barrels and drums, construction signs based on the Manual on Uniform Traffic Control Devices (MUTCD) and DOT standard details, and a truck with a mounted crash cushion.
NJDOT’s Division of Local Aid & Economic Development continues its efforts to make its project management processes more efficient by implementing electronic plan review. The Division is preparing to implement electronic plan review, a feature that was previously incorporated in the Project Management and Reporting System (PMRS), initially launched in 2021, to establish electronic document management, electronic plan review, and other 21st century project management innovations to make project management more efficient.
Training Sessions in an Innovation Context. The adoption of electronic plan review seeks to accomplish key goals aligned with the Department’s commitment to using technology to enable staff to perform routine tasks more efficiently. Ultimately, the transition to an electronic process will reduce paper consumption and centralize and standardize some project management activities. The shift will allow Local Aid project managers, NJDOT Subject Matter Experts (SMEs) and designers to collaborate efficiently, to enable easy file sharing and to track and manage the comment resolution process.
Local Aid’s objectives to improve program delivery through electronic review is well-aligned with EDC-3’s e-Construction initiative. The online training sessions targeted to NJDOT and Local Public Agency and consultants are being funded, in part, through a State Transportation Innovation Council (STIC) Incentive Funding Grant.
Each year the New Jersey STIC seeks to advance the deployment of innovations through the use of STIC Incentive Funding Grants. Click on NJ STIC Incentive Funding Grants to get more information on the purpose, eligibility and uses of NJ STIC Incentive Funding in recent years.
