Lane Closures Begin Friday On U.S. 231 Near Dale

New J-Turns to be Installed This Year

Dale (INDOT) – The Indiana Department of Transportation announces lane closures for U.S. 231 near Dale as crews begin working on a project that will install J-Turns at the State Road 62/Washington Street and State Road 62/68 intersections.

Contractors will set up intermittent alternating restrictions in both the north- and southbound lanes beginning Friday, Feb. 26, with a 12-foot width. Lane closures will last for the duration of the project and affect the area from one half-mile south of S.R. 62 to one half-mile north of S.R. 68. Restrictions will be in place around the clock, and work is expected to last into this summer, depending upon weather conditions.

Based on extensive study, INDOT has concluded that J-Turns will drastically improve safety at the two intersections of U.S. 231 and SR 62/68.

National statistics show a 35 percent decline in overall crash rates at intersections where J-Turns are installed, and a 54 percent reduction in injury crashes. This is achieved by reducing the number of conflict points that a motorist must navigate. A traditional intersection on a divided highway has 42 conflict points, 24 of which are right angle (T-bone) conflicts. A J-Turn intersection has 24 conflict points, and only 4 of them are right angle conflict points.

When completed, U.S. 231 traffic will still be able to go straight or turn left and right. S.R. 62/Washington Street and S.R. 62/68 traffic will not be able to go straight or turn left through the intersections. These movements will be made indirectly by first making right turns, traveling a short distance and making a legal U-Turn.

INDOT officials have taken steps to work with local residents in tailoring the intersections’ design to area specific needs including heavy truck and local farm traffic. Design improvements include:

  • Lengthened turn lanes in both the north- and southbound lanes to make it easier for trucks and farm traffic to safely maneuver into the proper lane.
  • U-Turns designed to accommodate standard tractor trailer length (73.5 ft)
  • Mountable curbs in the U-Turn sections for oversized vehicles
  • Extensive lighting for both maneuvers and for warning
  • An island median to allow for left turns while travelling U.S. 231
  • Non-mountable curbs in the island to discourage improper movements
  • Diagramatic signage

INDOT urges drivers to slow down and stay alert near crews. For construction updates and traffic alerts, follow INDOT on Facebook at www.facebook.com/INDOTVincennesDistrict and Twitter at www.twitter.com/INDOTSouthwest, or access INDOT’s TrafficWise website at http://indot.carsprogram.org.
