Design for the Replacement of Bridge 0-10 on Sunset Avenue over Deal Lake

Township of Ocean and The City of Asbury Park

PROJECT INFORMATION UPDATE

October 24, 2012

Monmouth County is proposing to replace the existing Bridge O-10 on Sunset Avenue over Deal Lake to

improve safety and access. Due to its age, it has deteriorated over time and with substantial chipping and

cracking, routine maintenance can no longer address the deficiencies.

The Project Background

The existing bridge is in poor condition. Several factors contribute to this poor assessment:

• Geometry: The width of the bridge is substandard and narrower than the approach roadway.
• Load Capacity: The non-redundant design is fracture critical and existing components are overstressed under modern design loads.
• Condition: Most of superstructure is in fair condition. Substructure is in poor condition due to significant scaling and spalling at piers and abutments.
• Highway Safety: Parapets or railings do not meet AASHTO crash standards and are in poor condition. Bridge attachments and end treatments also do not meet current design standards.
• Pedestrian Safety: Sidewalk condition and parapet condition are poor.
• Seismic: No rigorous analysis performed, however it appears vulnerable due to substandard bridge seat widths.

The Proposed Project

• Replace 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 project provides a consistent traveled way width and provides load capacity that meets modern design standards.
• The project corrects Highway Safety and Pedestrian Safety deficiencies by correcting sidewalk, shoulder, and parapet deficiencies.
• The bridge seats and bearings will provide a structure that meets current guidelines for seismic vulnerability.
• Significant aesthetic features will be carried forward in to the replacement structure’s design, with an emphasis on haunched fascia appearance, decorative lighting, and cantilever overhangs.
• Navigation clearance for boaters will essentially remain the same.

Project Cost

The construction costs are estimated at $10.4 million. Federal funding is administered through the State Local Aid program for this project.

Project Schedule

Design Considerations

• Aesthetics and maintaining the general character of the existing structure on the new replacement bridge.
• Duration of construction phases/Constructability.
• Long-term maintenance requirements.
• Incorporation of roadway safety improvements, especially sight distance and pedestrian/bicycle safety.
• Right-of-Way constraints challenge construction staging availability.

Environmental Factors

• Construction timing restriction will limit duration of in-water work.
• Disturbance thresholds will be kept to a minimum.
• Water quality impacts during construction.

Community Involvement

Prior local officials briefings and public meetings have resulted in Resolutions of Support by both Ocean Township and the City of Asbury Park for the project to move forward to the design phase of the project. Current community outreach meetings held with local officials, community and agency stakeholders:

• Community Stakeholders Outreach Meeting No. 1 – March 15, 2011
• Ocean Township and City of Asbury Park Traffic Technical Meeting No. 1 – April 28, 2011
• Community Stakeholders Outreach Meeting No. 2 – June 6, 2011 (5:00 p.m. – 6:00 p.m.)
• Monmouth County Bridge BRO-10 Public Forum – June 6, 2011 (7:00 p.m. – 9:00 p.m.)
• Community Stakeholders Outreach Meeting No. 3 – October 25, 2011
• Community Stakeholders Outreach Meeting No. 4 – October 24, 2012

Coordination and information exchange with the communities and stakeholders will continue through the final design and construction phases.
