New Jersey's second precast concrete segmental bridge will serve as a gateway to the seashore towns of Sea Bright Borough and Sandy Hook and connect with Highlands Borough on the mainland, in Monmouth County, N.J. The nine- span twin bridges have main spans of approximately 232 ft. Each structure will be approximately 1611 ft long with a deck width of approximately 46 ft. The bridges cross the Shrewsbury River and will ultimately replace a functionally obsolete and structurally deficient 75-year-old, double-leaf bascule bridge. The eastbound structure is complete and open to traffic. The remainder of the bridge is scheduled for completion in 2010. Until it was demolished earlier this year, the bascule bridge had 11-ft-wide l a n e s a n d l a c k e d s h o u l d e r s . T h e bridge's obsolescence created extensive congestion especially during the summer months when the shores along the Atlantic Ocean are visited by beach goers. The bridge opened twice an hour for maritime traffic on the Shrewsbury. The new bridges will provide 65-ft minimum vertical clearances above mean high water in the navigation channel and upgrade the width of the travel lanes to 12 ft and add 8-ft-wide shoulders. From the onset, community participation was important to the New Jersey Department of Transportation (NJDOT). In 2001, NJDOT established the Community Partnering Team (CPT) to inform community stakeholders and the public of project development and progress. As defined by NJDOT, the membership o f t h e C P T i n c l u d e d m u n i c i p a l , organizational, and agency members; invited guests; special task forces; and NJDOT staff. A steering committee comprised representatives from the F e d e r a l H i g h w a y A d m i n i s t r a t i o n , NJDOT, local government, and the design consultant. CPT Task Forces were created for aesthetics, bike/pedestrian connections, environmental coordination, traffic, and communications. For more than a decade, NJDOT conducted numerous meetings with local officials and residents via the CPT. In addition to the new bridges, the project will also include intersection improvements in Highlands and Sea Bright, pedestrian/bicycle access paths on and off the bridges, construction of two pedestrian bridges, and modifications to the Gateway National Recreational Area toll plaza at Sandy Hook. profile ROUTE 36 HIGHLANDS BRIDGE OVER THE SHREWSBURY RIVER / BOROUGHS OF HIGHLANDS AND SEA BRIGHT AND TOWN OF SANDY HOOK, MONMOUTH COUNTY, NEW JERSEY DESIgN ENgINEEr: Jacobs Civil Inc., Iselin, N.J.
