HWC was assigned to provide design services for the US 50 HMA Overlay project under the INDOT On-Call contract in the Seymour District. HWC extended the functional life of the asphalt overlay by addressing cracks at joint deterioration and longitudinal cracks by construction of partial and full-depth patching of the underlying concrete pavement and application of a 2” mill/fill of the asphalt surface.

 Additionally, HWC brought 90 curb ramps to current ADA standards, as well as updated the nine existing traffic signals to have APS devices installed where applicable. This project included two DES numbers, and HWC worked with the District under time constraints to deliver both projects. The project was completed in 2023.

HWC provided roadway design, erosion control permitting, IDEM water permits, small structure design, right-of-way plan development, and public hearing coordination services.

HWC worked with INDOT to develop a solution to keep SR 66 open during construction by utilizing temporary portable traffic signals during the phased construction of the box culvert and a multi-phased plan for the reconstruction of the intersection.

Project let in April 2018 at a cost of $1,300,000, which was 5% below the engineer’s estimate.
