As the Wisconsin Department of Transportation’s first ever design-build, the WIS 130 Lone Rock Wisconsin River Bridges project is not only restoring critical connection and improving safety but setting a new precedent for WisDOT’s use of the alternative delivery method.

The Project

Currently in construction, HNTB is helping replace three existing, 80+ year old, steel truss bridges with two prestressed, multi-segmented, girder bridges. At approximately 1,000 feet each, the new bridges will carry WIS 130 and 133 over both channels of the Wisconsin River.

HNTB serves as the Owner’s Representative, providing construction engineering and inspection (CEI) services. Due to its rural location, moderate travel rate of 2,500 vehicle per day and the existing bridge’s limited service life, the project was determined as an ideal choice for WisDOT’s first use of design-build to expedite the project.

Putting Safety First

The bridge replacements aren’t only testing a new delivery approach for Wisconsin. The project is improving safety and restoring a connection that communities on both sides of the river can rely upon.

To affirm the safety of future commuters, a critical element of the work includes realigning an existing T-intersection located at the south side of the river. As the crossing runs along a steeply sloped rock bluff, HNTB is helping to shift the WIS 130/133 intersection 1,000 feet to the west, thereby eliminating any potential dangers to future motorists on the new bridges. The project will also add an eastbound bypass lane, a westbound right turn lane and beam guards to help minimize traffic hazards.

A Dependable Delivery

Upon completion, the success of the Wisconsin River Bridges project will renew a vital transportation link for surrounding communities and, as design-build further proves to be a dependable mode of delivery for WisDOT, help usher forth new possibilities for the state’s future transportation infrastructure initiatives.
