The new northbound ramp from Keystone Parkway to US 31 opened last night nearly two weeks ahead of schedule. The former ramp closed on July 30 as part of the reconstruction and upgrade to the freeway-style design of the new US 31 in Hamilton County.
The new ramp carries Keystone Parkway on a new alignment over two new bridges that span Cool Creek, the Hagan-Burke Trail and a future northbound US 31 exit ramp to 146th and 151st Streets.
Walsh Construction, the state’s contractor, estimated an 80-day ramp closure in a bidding process that had contractors compete on both cost and closure time. With the ramp opening nearly two weeks ahead of its schedule, Walsh is eligible to receive financial incentives.
In addition to more efficient US 31 ramp motions to and from Keystone Parkway, the interchange upgrade is creating a ramp system connecting US 31 and 146th Street. As construction of the interchange continues, northbound US 31 traffic will continue to share the west side of the roadway with southbound traffic between the Monon Trail overpass and Greyhound Pass. It is anticipated that all traffic will be shifted into its permanent configuration before the end of the year.
The interchange construction is part of a Major Moves program to upgrade or bypass congested sections of US 31 between Indianapolis and South Bend. Upgrading the existing highway between I-465 and State Road 38 to interstate standards will be the largest and most aggressive road project ever implemented in Hamilton County. The US 31 Hamilton County project is intended to reduce congestion, improve safety and provide continuity of commerce and regional travel for a US highway that stretches from Michigan to Alabama.
