U.S. 63 OVER CHICAGO CENTRAL & PACIFIC RAILROAD

WATERLOO, IA

BACKGROUND

Due to frequent flooding of U.S. 63 under the railroad bridge in Waterloo, the Iowa DOT designed a new grade separation to raise the elevation of U.S. 63 over the Chicago Central and Pacific Railroad. The new overpass will help emergency responders access the hospital just north of the project, as well as improve vehicular and pedestrian traffic in the area. Peterson Contractors Inc. sought to use stay-in-place forms to speed placement of the deck due to limited work windows above the active railroad and avoid additional flagging time and man-hours removing the temporary wood deck formwork.

BERKELEY AVENUE/I-5 SOUTHBOUND ON-RAMP BRIDGE

LAKEWOOD, WA

BACKGROUND

To improve traffic flow at the Berkeley Avenue SW and I-5 interchange in Lakewood, the Washington DOT required the replacement of the bridge over I-5, including construction of a new on-ramp bridge for traffic heading southbound on I-5. Atkinson Construction contacted TrueTech Bridge for a stay-in-place form option that would increase productivity and safety for their crews on site, while still allowing for long-term visibility to the bottom of the deck for inspection. This was a major milestone in bridge deck construction in the state of Washington, as WSDOT had not previously allowed the use of stay-in-place forms in the state prior to this project.

ISTHA EDENS SPUR (I-94) OVER METRA RAILROAD

COOK COUNTY, IL

BACKGROUND

As part of the Illinois Tollway’s 15-year program “Move Illinois: The Illinois Tollway Driving the Future”, a bridge constructed in 1958 was required to be removed and replaced to improve traffic flow along Edens Spur (I-94), with daily traffic of up to 57,000 vehicles. Walsh Construction partnered with TrueTech Bridge for a stay-in-place form option that would increase productivity and safety for their crews while working over the active Metra Railroad. While the Illinois Tollway traditionally has not allowed conventional stay-in-place forms, they were open to using ClearCast Forms as an alternative to removable forms. This decision led to reduced railroad flagger costs during construction, and will allow for future inspections of the bottom of the deck.

I-29 OVER PERRY CREEK

SIOUX CITY, IA

BACKGROUND

A new ramp along I-29 in Sioux City, Iowa, required an 85 ft. bridge to span over an aging conduit carrying Perry Creek. Precast Bulb T-Beams were set just above the existing conduit, resulting in low headroom between the two structures. Cramer & Associates sought to use stay-in-place forms to speed placement of the deck and avoid the tedious task of constructing and removing temporary wood deck formwork.

FRANKLIN AVENUE OVER I-35 WEST

MINNEAPOLIS, MN

BACKGROUND

To improve transit and public access to the Lake Street Business District along I-35W, MnDOT undertook the 35W at 94 Downtown to Crosstown project. The project required replacement of the Franklin Avenue Bridge, which carried communication conduit over I-35W. Once new Precast Bulb T-Beams were set in place, there was limited space to safely strip the deck forms from below due to the duct bank. Lunda Construction and MnDOT contracted TrueTech Bridge for a stay-in-place form that would both accommodate the duct bank and enable long-term visibility.
