Reconstruction of Bronx Approach of Whitestone Bridge

The Bronx-Whitestone Bridge connects the Boroughs of the Bronx and Queens, New York. 

In order to reduce the dead load on the structure, the outboard stiffening trusses were removed and the bridge deck replaced with new aerodynamic precast panels. 

SIMCO prepared the design for the Maintenance of Traffic during the staged reconstruction.  The deck was removed and panels installed using a moving gantry during off-peak traffic hours, nights and weekends.  This project was completed in 2005.

For the reconstruction of The Bronx approach to the Bridge, SIMCO conducted a traffic analysis and prepared revised Maintenance of Traffic plans for the staged demolition and reconstruction of the Bronx approach to the suspended span. 

This project utilized a “zipper” moveable barrier with a slender traffic barrier cross section to maintain directional traffic lanes based on peak hour traffic demand.  The project was completed in 2013.

SIMCO coordinated the project with the MTA Bridges & Tunnels and the NYCDOT Office of Construction Mitigation and Coordination (OCMC).

The services included:

  • Field Traffic Data Collection
  • Traffic Analysis and Modeling
  • Toll Plaza Operations Coordination
  • Maintenance of Traffic
  • All-Agency Coordination
