The Indiana Department of Transportation is planning to work on Sendelweck Curve next spring to make it less curvy.

Sendelweck Curve is on State Road 56 east of Haysville. It starts 2.6 miles east of U.S. 231, and has been the site of several accidents over the years.

Mary Wright of INDOT, said the state has received many comments of concern over the years from the public about the curve. “We know that the community is behind this,” she said.

The plan is to realign that section of the state road south of the existing road to improve the sight distance for drivers. INDOT will use state and federal funds to cover the project’s cost, estimated to be $2.3 million.

“It isn’t just about straightening the curve,” Wright said. “This is also going to level it out, smoothing out the dips.“

Sendelweck Curve is actually two curves going in opposite directions, making an S shape. The speed drivers are to drive on State Road 56 is 55 miles per hour, but when approaching the S curve, the speed limit lowers to 35 miles per hour. Signs, rumble strips and flashing lights warn drivers of the upcoming curve. However, some drivers still do not heed the signs in time, causing accidents.

According to INDOT, 33 accidents occurred near Sendelweck Curve between 2010 and 2014; 11 of those happened within the curve and five occurred within a quarter of a mile of the curve. One accident was a fatality.

Wright saw proof of that when she used Google to look at the curve. “I did notice that there are tire tracks off into the grass on part of the curve,” she said.

The environmental report for the work needs to be finalized by the state. Once that is done, the state will start working on acquiring property. “And then it will go to construction,” Wright said.

When construction starts, the section of the road will be closed to traffic for about 60 days, INDOT officials have indicated. The official state detour will utilize U.S. 231, State Road 164, State Road 545 and North County Road 500 East.

School corporations and emergency crews will be notified and kept updated on any limited road access while the road is under construction.
