Creek Road Bridge

PROJECT SCOPE

This project replaced the existing wooden structure originally built in 1935 over the WSOR railroad. The bridge had been closed to traffic for 8 years before construction began. Vertical curve adjustments were made to accommodate the new structure’s height above the tracks. MSE walls were built to elevate the bridge and narrow the span across the railroad. In addition, a realignment of Hofstrom Road was required to meet current safety standards.

CHALLENGES FACED

• This project required utilizing local township roads for hauling construction materials; some of these roadways were in unstable condition and are not rated to carry the loads required for projects such as this.
• Roadway realignment through farmland presented unsuitable soil conditions.
• Three high-pressure gas mains crossed the roadway near the west project limit. No compaction equipment was allowed over the top of these lines.

SOLUTIONS IMPLEMENTED

• Coordination with the Town of Bradford and Rock and Walworth County officials allowed us to use the best routes to access the project.
• Project staff coordinated with the contractor and WisDOT to ensure the roadway portions constructed over farmland were excavated and covered with roadway base in a timely manner to prevent drainage issues and soil instability.
• Project staff worked directly with the gas company and the contractor to produce alternate subgrade stabilization techniques to complete the roadway over the gas mains.

Field Data: 5,560 SF of MSE Walls, 7,400 CY Borrow, 227 CY Concrete Masonry Bridges
