Lawson-Fisher Associates was selected for this project which entailed construction of new bridges, widening and rehabilitation of existing bridges, and extensive use of MSE retaining wall construction. MP 17 is the interchange for both U.S. 20 and I-65 with the Toll Road. All construction was done under traffic, making the safety of the workers and motoring public a major concern throughout the project. Although Lawson-Fisher Associates did not design the initial project, Mr. Riemke, of Lawson-Fisher Associates, played a key role in all ongoing construction engineering decisions.
