The new double-crossover diamond interchange at Campus Parkway and Interstate 69 (Exit 210) is nearly complete and is anticipated to open to its final traffic pattern next week. Additional lanes will be opened in both directions over I-69 and on some interchange ramps.
Milestone Contractors plans to pave surface asphalt and apply final pavement markings starting Monday night, July 31. In order to complete the work more safely and efficiently, the interchange will be partially closed each night next week between 9 p.m. and 6 a.m.
Campus Parkway access over I-69 will be closed. The Campus Parkway entrance ramps to I-69 and the I-69 exit ramps to Campus Parkway may be closed. Electronic message signs and police will advise motorists of the closures and direct traffic to the Olio Road overpass to cross over the interstate during the overnight operations.
Weather permitting, the interchange is expected to be complete and open in its final configuration and capacity by the end of the week. Some additional work may remain with little to no impact to traffic.

About the double-crossover diamond interchange
Two similar interchanges have been constructed with success in Indiana. The first was at I-69 and Dupont Road in Fort Wayne, and the second was built at I-65 and Worthsville Road in Greenwood.
This interchange design may appear unusual, but by following signs, pavement markings and traffic signal instructions, drivers find these interchanges easy to navigate.
Right turns at double-crossover diamond interchanges are very similar to traditional intersections.
For traffic crossing the Campus Parkway bridge over I-69, traffic signals, signs and pavement markings briefly shift traffic to the left side of the road. This allows left-turning traffic to flow more freely as it enters and exits I-69.
Through traffic on Campus Parkway shifts back to the right side of the road at the next traffic signal.
Added travel lane construction
Widening Campus Parkway at I-69 and building the double-crossover diamond interchange is part of the $92 million I-69 Major Moves 2020 project adding a travel lane to each direction of I-69 between State Road 37 (Exit 205) and State Road 38 (Exit 219). In addition, other improvements are being made to rehabilitate existing bridges, pavement and drainage structures on the 15-mile stretch of interstate.
Two lanes of traffic in each direction of I-69 are currently shifted to accommodate construction of the additional travel lanes. Signs direct large trucks to use the left lane while traffic is shifted toward the right shoulder through the work zone. The speed limit is reduced to 60 mph and further reduced to 50 mph when workers are present.
I-69 is expected to open to three lanes in each direction between State Road 37 and State Road 38 before the end of this year.
