I-44 MEDIA RECONSTRUCTION
Engineering a Stronger Community: Saving lives and reducing crashes on I-44 by removing ponding water from shoulders and lanes
This section of I-44 was widened in 1995 from four lanes to six by eliminating the grass median and replacing it with the two additional lanes and shoulders. As a result, the profile for this section of highway is very flat with long segments at zero percent grade, resulting in pooling of water and causing hazardous road conditions.
CDI provided an evaluation of the drainage issues along this section of median and developed a set of alternatives for its reconstruction. The new shoulders drain toward existing inlet locations, which have been reconstructed at lower elevations. Final plans and cost estimates were developed for several alternative methods of reconstructing the shoulders to provide for improved drainage.
