“Dogbone” Construction to Start at I-65 and 109th Ave
The Indiana Department of Transportation will be closing 109th Ave from Delaware Pkwy to Mississippi St and all of the ramps at the I-65 and 109th Ave interchange beginning Tuesday, June 1.
These closures are to replace the two signalized intersections with roundabouts, known as a “dogbone” interchange, and widen 109th Ave to four lanes. Work will be ongoing through mid-November, 2021.
The official detour for 109th Ave will follow State Road 53, U.S. 231, Iowa St, 113th Ave and Mississippi St. Motorists are encouraged to use the U.S. 231 interchange as an alternative for entering/exiting I-65.
Similar dogbone interchanges are located at State Road 49 and Vale Park Rd/C.R. E 400 N in Porter County and U.S. 20 and State Road 2 in LaPorte County.
In conjunction with this project, the City of Crown Point will be widening 109th Ave to the west so that it is four lanes from Broadway/State Road 53 to the I-65 interchange. They will also be constructing a roundabout at the intersection of 109th Ave and Iowa St to the east of this interchange project.
