Motorists travelling southbound on S.R. 37 are advised to avoid S.R. 37 at S.R. 44 south to Crossover Road area from approximately 10:30 a.m. to 2 p.m. on May 19.

Heavy traffic delays are expected while the transformer is in transit. An alternative route is highly encouraged. If traveling south from the Indianapolis area, consider using S.R. 67 to Spencer and S.R. 46 to Bloomington. Motorists traveling behind the transformer should exit S.R. 37 on Old State Road 37 south of Martinsville and continue to S.R. 45/46 into Bloomington.


The trailer and transformer will be traveling at an average speed of 10 miles per hour or less.


On Friday, May 20, a second move will take place between 9 and 10 a.m. to complete the unit’s transfer to the substation. That move is expected to impact southbound traffic for 30 minutes depending upon traffic and the difficulty in making the turn from S.R. 37 to the south entrance of Crossover Road.
