Engineers in Oklahoma City Seek to Replace Deficient Bridge

Feb. 28, 2024
The project would cost $10.5 million

On Tuesday, engineers in Oklahoma City presented preliminary design reports for a project to replace a deficient bridge carrying N May Avenue over Northwest Expressway.

According to the reports, the project would cost $10.5 million.

The bridge's height limit is lower than modern standards and it has partially collapsed twice from trucks hitting crossing beams.

The project would replace the current bridge with a 260-foot long and 75-foot wide steel I-beam span bridge, implementing a diverging diamond interchange design.

Other proposed improvements include:

  • reconstruction of the on- and off-ramps;
  • new traffic signals for a new intersection at the crossover traffic point;
  • building a 10-foot trail along the center of the bridge; and
  • adding ADA-compliant sidewalks, bridge rails and traffic parapet barriers.

Public Works Director Debbie Miller said city staff and engineering consultants researched less expensive options, but the $10.5 million proposal was the option city planners recommended because it would offer the biggest improvement to traffic safety and because it was the only one the association grant would support.

Miller said plans should be finalized in late 2024 and construction should begin in 2025.
