Research Park Boulevard (SR 255) between U.S. 72 and Old Madison Pike

Published on April 24, 2017


This project includes adding two additional lanes in the center along Alabama 255 (S.R. 255) between U.S. 72 and Old Madison Pike. The project will also include a new bridge at Old Madison Pike to include 10 feet of multi-use paths on each side to accommodate pedestrians and cyclists and will include a new bridge along the Bradford Drive northbound on-ramp and new MidCity off-ramp along S.R. 255.

The project will be constructed in two phases:

Phase I: Additional lanes added in the median with new barrier wall between U.S. 72 and to an area just before Old Madison Pike. Construct new Bradford Drive bridge and remove old ramp, followed by construction of the MidCity ramp.

Phase II: Old Madison Pike bridge replacement will be stage constructed to keep traffic across the bridge during construction. Connect the barrier wall to center pier for the new bridge at Old Madison Pike. Widen outside lanes on S.R. 255 after traffic is switched to the new center lanes. Leveling and paving of S.R. 255 while keeping traffic in two lanes in each direction. Install new sign bridges, final paving, striping and signage.


Improvements along Research Park Boulevard are approximately 97% complete. The contractor has completed the overhead signs and the center barrier wall. The contractor has paved the final wearing lanes for most of the project, allowing the traffic shift to the inner portion of the roadway so remaining sections can be widened.

The Old Madison Pike bridge is complete with new sidewalks on both sides of the bridge. Traffic will continue to have one lane in each direction along Old Madison Pike within the work area until paving is completed. The anticipated completion date for the entire project is late August, weather permitting.
