Stopping -- <br />I <br /> sight distance is the absolute minimum sight distance that should be provided anywhere on the - <br /> roadway. The desired stopping sight distance at a design speed of 50 miles per hour, which is the - <br />I design speed for most segments of Highway 96, is 475 feet. The analysis for the 1989 TH 96 Task <br /> Force Study Report found that several segments have one or more locations with sight distance ~ <br /> restrictions.

The design of the side slope should also take into <br /> account maintenance needs. The desirable side slope for fill areas is 6: I and for cut areas is 3: 1. - <br /> <br />.. - Many of the fill side slopes on Highway 96 east of Lexington are either 2:1 or 3:1. - <br /> - <br /> 5 <br /> ~ <br />I ~ <br /> - <br />
