SR-87/Capitol Expressway Interchange Improvement

The SR 87/Capitol Expressway Interchange Improvement project will improve vehicular access between northbound SR 87 and Capitol Expressway, provide high-quality, convenient, and comfortable accommodations for active transportation (bikes and pedestrians) and provide seamless connections between all modes of transportation.

The project will eliminate the existing hook ramps in the northbound direction connecting to Narvaez Avenue and instead replace them with a direct connection to Capitol Expressway. It will reconfigure the Capitol Expressway cross section to provide all the necessary travel lanes, bike facilities (Class IV bikeways), and pedestrian accommodations.

Narvaez Avenue will be right-sized to accommodate all transportation modes as well. The Capitol Expressway intersections will be squared up and upgraded to enhance service to bicycles and pedestrian users while maintaining a high level of service for vehicular traffic and LRT station access from Capitol Expressway will
be reconfigured.
