Rehabilitation of U.S. 130 Bridge over Big Timber Creek

Location: Brooklawn Borough, Camden County and Westville Borough, Gloucester County, New Jersey

Client: McCormick Taylor, Inc.

Owner: NJDOT

Phase: Preliminary Engineering and Final Design

Status: Construction Underway

The New Jersey Department of Transportation commissioned McCormick Taylor, Inc. to provide Preliminary Engineering and Final Design phase services for this multicounty bridge rehabilitation project.  In the Preliminary Engineering phase, KMA was retained to provide surveying and mapping, utility engineering (including SUE), perform pavement testing and design, conduct preliminary geotechnical investigations and analyses, and perform soil investigations for stormwater management design.

In the Final Design phase, KMA performed supplemental surveying (wetland lines and stream cross-sections), additional SUE (test holes), and completed final geotechnical investigations and analyses.

For the pavement design, KMA conducted field work consisting of falling weight deflectometer testing, dynamic cone penetration testing, pavement coring, and collection of bulk soil samples for laboratory testing.   KMA’s resulting pavement design report served as the basis for pavement structure improvement of U.S. Route 130 and the adjoining Brooklawn Circle.  For the geotechnical investigations and analyses, a total of fourteen borings were drilled, ten on land and four under water.  Geotechnical analyses performed included those on deep foundations, pile load capacities, seismic exploration, vertical stress influence, and spread footing.  KMA compiled a comprehensive geotechnical engineering report encompassing all on-site and laboratory findings and design recommendations.
