KCC was awarded the replacement of Bridge 0-10 by Monmouth County to improve safety and access.

Due to its age, there had been deterioration as well as chipping and cracking that could no longer be addressed by routine maintenance. The intent of the new bridge was to build a similar structure with modern material and design elements. The project spans across Deal Lake, which presented access obstacles along with the overly soft lakebed soil and required environmental guidelines. The logistical and operational challenges were strategically met and achieved by the KCC’s resources through innovative methods creating support for the concrete structure to ensure a safe and successful outcome.
- Replaced previously existing five (5) span with a four (4) span structure with arched fascia
- One 12-ft lane in each direction with 6-ft shoulders and 6-ft sidewalks
- The bridge provides a consistent traveled way width and provides load capacity that meets modern design standards
- The bridge corrects Highway Safety and Pedestrian Safety deficiencies by correcting sidewalk, shoulder, and parapet deficiencies
- The bridge seats and bearings now provide a structure that meets current guidelines for seismic vulnerability
- Navigation clearance for boaters essentially remains the same
- Concrete was used to its advantage in order to provide and carry forward the historically aesthetic features in the replacement structures design, maintaining the general character of the existing structure with an emphasis on a haunched fascia appearance
- NJDOT, high-performance concrete was utilized in the deck and Class “A” was required in the sidewalks and parapets
- Innovations included building custom forms for the pier shafts and also the requirement of a thermal control plan for the curing of the concrete
- Approximately 2500 total cubic yards were used
- Access to the lake bottom for concrete pier construction with heavy equipment was obtained through the innovative use of specialty matts and a perimeter cofferdam
- KCC was required to provide flow calculations to support assurances that the proposed perimeter cofferdam necessary to construct the in-water piers would not contribute to flooding
- Construction timing restriction was limited for the duration of in-water work given NJDEP regulations of which to protect the fish migration and ecological sensitivities
- Disturbance thresholds were kept to a minimum in order to sustain the ecosystem
- Water quality impacts during the construction were strictly upheld for environmental safety
