Motorists traveling on North Keystone Avenue at Interstate 465 will be routed to newly completed west side lanes Thursday night to make room for construction on the east side of the roadway. Both northbound and southbound Keystone traffic will be impacted by the traffic switch.
At the same time, the Indiana Department of Transportation will close the westbound I-465 ramp to southbound Keystone for 10 to 14 days. This will allow Reith Riley, the state’s contractor, to complete construction of the off ramp—connecting it to the new pavement on the west side of Keystone.
Meanwhile, the eastbound I-465 ramp to northbound Keystone will reopen. Drivers will have two northbound AND two southbound ramp lanes accessing Keystone Avenue.
A single ramp lane from westbound I-465 to northbound Keystone will remain open.
INDOT hopes to open the new ramp system for northbound Keystone to both eastbound and westbound I-465 on Thursday night. But sufficient concrete curing may push this ramp opening to Friday night.
This $18.2 million Major Moves project is reconstructing the Keystone Avenue/Interstate 465 interchange as a partial cloverleaf. In the future, there will be free-flow traffic movement on two loop ramps from northbound Keystone to westbound I-465 and southbound Keystone to eastbound I-465 to reduce traffic congestion. The project includes added travel lanes—one in each direction on Keystone—plus added turn lanes from just south of 96th Street to 98th Street.
