Indiana Toll Road 80/90 PUSH, Phases I & II

JSE was the prime consultant on this project providing road and bridge design services. JSE performed extensive traffic analysis considering different times of the year to estimate queue lengths in order for the contractor to determine their construction windows and the maximum length of construction zones. Detailed maintenance of the traffic scheme was developed by JSE that included interchange closures, as necessary, detour routes, and phased construction on the mainline.

The project required every bridge to be inspected in order to generate a durability report to confirm the amount of rehabilitation required on each bridge. The durability report served as the scope document for which final plans were developed. All structures were required to meet minimum performance criteria defined by the owner. Post-construction, JSE performed the bi-annual inspection and load rating of every bridge included in this project.

PHASE I

The 80/90 PUSH Project is a major rehabilitation and upgrade of a 73-mile section of the Indiana Toll Road (I-80 / I-90) between the cities of Lake Station and Elkhart. The existing mainline asphalt pavement was milled off and the underlying concrete pavement was crack and seated to accept a new pavement section. The project also required various types of bridge rehabilitation on 53 structures.

PHASE II

The 80/90 PUSH Project is a major rehabilitation and upgrade of a 10-mile section of the Indiana Toll Road (I-80 / I-90) between the Illinois State line and Exit 10 interchanges (SR 912) in Gary. The existing mainline asphalt pavement was milled off and the underlying concrete pavement was crack and seated to accept a new pavement section. The project also required bridge deck replacements on 16 structures.
