LKB received a Project of the Year Award for the study, preliminary design, final design and construction support of this new exit ramp on the Bronx River Parkway.
This project required the design of a 1,000-foot long ramp in a narrow corridor located over the Bronx River between the Bronx River Parkway and a Metro North rail line. The ramp elements include a four-span, 600-foot long steel bridge that connects to an existing bridge above the river and two steel sheet piling retaining walls with a combined length of 500 feet. The bulkhead wall design included the use of helical anchor tie backs.
Other work included vehicle projections, traffic analysis and traffic signal design plans, survey and mapping, preparation of Design Approval Documents (DR/EA) for Federal funding, environmental permitting, a hydraulic analysis, the preparation of a soils report, construction support services, and public hearings and meetings.
