A project to install a new pedestrian bridge over U.S. Highway 75 north of Lyndon was scheduled to begin Tuesday, according to the Kansas Department of Transportation.

The project is located approximately .28 miles north of the junction of U.S. 75 and state highways 31 and 268. It includes the removal of the 80-year-old railroad bridge over U.S. 75, grading to widen the slopes adjacent to the bridge, addition of paved shoulders, and installation of a pedestrian bridge.

Sometime during the project, U.S. 75 will be closed for approximately three days to remove the existing railroad bridge and another three days to install the new bridge. Advance notice will be given when the closures are scheduled.

A marked detour will be provided during the closures. Northbound traffic will take K-31 west to Osage City, then north on U.S. Highway 56 to Burlingame, then east on U.S. 56 to U.S. 75. Southbound traffic will follow the reverse of this detour.

There will also be some flagging possible when crews complete paving work on the shoulders, although no work is to be done on the pavement of U.S. 75. Drivers should expect some delays and are encouraged to use alternate routes, if possible.

TL Enterprises, Inc., is the primary contractor on the $887,364 bridge project, funded by the American Recovery and Reinvestment Act of 2009. The scheduled completion date for the project is late October.

The pedestrian bridge will allow the Flint Hills Nature Trail to cross the highway. The trail, which follows the old Missouri Pacific rail line, has portions completed near Vassar, although the portion of the trail west of U.S. 75 to Osage City is undeveloped.
