Bridge Rehabilitation / Widening

Walter Webb Bridge (North Road Bridge)
Hillsboro, IL

Three-span bridge was built in 1923 and has been in continuous service since that date. The proposed replacement structure will be a three-span PPC I-beam bridge, integral abutment configuration with double hammerhead piers adjacent to the streambed. The roadway will be realigned to allow construction of the new structure while maintaining traffic on the present bridge. Borrow for the project will come from an abandoned railroad embankment north of the site. Bridge approaches of 0.6 mile (rural section) and 0.15 mile (urban section including storm sewers) are included in the project limits.

Lake Hillsboro Spillway Bridge
Hillsboro, IL

Hurst-Rosche provided engineering services necessary to construct a replacement bridge over the spillway of Lake Hillsboro, including the east and west approach roadways to the replacement bridge. The bridge length was 100 feet and bridge width was 24 feet.

FA 805 (Illinois Route 161)
Crossing Dutch Hollow Road, CSX Railroad, and Schoenberger Creek
St. Clair County, IL

The design services for this project included TS&L development (alternative bridge configurations and comparative estimates of cost), preliminary and final design, special provisions, and estimate of construction cost. The construction was dual four-span continuous, composite, welded plat girder bridges. Special seismic design incorporating seismic isolation bearings and special abutment design for negative skin friction loads was used in the construction of this project. Pier height was a maximum of 56 feet.

MD Route 43 / I-695

MD Route 43 / I-695 consisted of a three (3) span curved girder over I-695 and dual steel girder bridges on I-695. Continuous span curved steel girder bridge over I-695. Continuous span steel girder bridge on U.S. Route 1 over MD 43. Replacement of dual steel girder bridges on I-695 over Avondale Road. Five structural plate pipe culverts. Five retaining walls (total length of 2500 feet).

Fernwood Road over I-270

Fernwood Road over I-270. This project consisted of the design and construction of a 3-span bridge across Interstate I-270, together with approximately 1,500 linear feet of new approach roadway, major retaining wall, storm drains, inlets, PEPCO and Bell Atlantic underground conduit and manholes, and water facility adjustments. Hurst-Rosche provided complete design, construction document preparation and primary construction administration, and inspection services for this project.
