Switzerland County, In. — Contractors replacing two bridges for the Indiana Department of Transportation on State Road 56 in Switzerland County will begin operations in mid-September.
Milestone, INDOT’s contractor for the $3,695,455 project near Lamb, plans to clear the S.R. 56 Tucker Run site during the second week of September. Once cleared, temporary signals will be installed before actual construction—replacing one-half the bridge at a time—starts on or after October 1. Single-lane traffic flow will be controlled by the temporary signals.
The new S.R. 56 Tucker Run bridge will be a 3-span concrete bulb-T structure measuring 200 feet in length with almost 33 feet of clear roadway side-to-side.
A second S.R. 56 bridge located less than a mile west of the Tucker Run structure will be removed and replaced after the first of the year. The S.R. 56 Green Valley Creek bridge is a single-span I-beam structure measuring 68 feet in length and 30 feet side-to-side. Clearing should begin this October, followed by utility relocations. Actual construction activities are slated to start in January.
Approximately 1000 feet of new pavement will be put in place to realign S.R. 56 north of the current Green Valley Creek structure. This will allow continuous free-flow traffic at the site until pavement tie-ins occur. At that time, a 14-day closure will be imposed to complete the connection.
S.R. 56’s traffic count is 2,257 vehicles per day.
