130 PCIJOURNAL Dedication of Bridge Street Bridge, Southfield, Michigan — First CFRP Reinforced Bridge in the United States

Side view of the first CF’ ge constructed in the United States.

he City of Southfield, Michigan, held a dedication ceremony on May 8, 2002, for the opening of the T Bridge Street Bridge — a premier carbon fiber rein forced polymer (CFRP) bridge. This project marks the first time this technology has been used in a highway I bridge in the United States. The design was based on research funded by the Na tional Science Foundation and conducted at Lawrence Technological University, Southfield, Michigan, under the direction of Nabil F. Grace. Dr. Grace was on hand for the opening ceremony, along with Southfield Mayor Brenda Lawrence, City Administrator Donald Gross, and representatives of the Japanese CFRP manufacturers. Others collaborating in the construction include Angelo lafrate Construction Co.; Autocon Composites, Inc.; Construction Technology Laboratories, Inc.; Hollowcore, Inc.; Hubbell, Roth, & Clark, Inc.; Mitsubishi Chemical, Inc.; Mitsui USA; Sumitomo Corp. of America; The Pre stressed Group; and Tokyo Rope Mfg. Co. This project will provide an objective evaluation of the performance of carbon fiber reinforcement versus con ventional steel. Parallel concrete bridges over the Rouge River replaced an obsolete steel bridge at the only access point to the Bridge Street Industrial Park. The first new I bridge, opened to traffic in the Spring of 2001, was con structed with standard AASHTO Type III bridge girders with conventional steel prestressing strands. This is the second bridge, which has been constructed using twelve double tees reinforced with CFRP components. Federal funding will allow both bridges to be monitored for a pe riod of five years using a sophisticated sensor system. The design, construction, and monitoring of this pro ject, which recently won PCI’s prestigious Harry H. Ed Underside view of Bridge Street Bridge showing the wards Industry Advancement Award, is covered in detail external tendons and anchorage for CFRP post-tensioning in the feature article beginning on page 20. components.

September-October2002 135 Shockey Masters Tight Fit

In August of 2002, The Shockey Pre cast Group, based in Winchester, Vir ginia, began erecting a tight addition to the HBL Mercedes Parking Structure. Located in Tysons Corner, Virginia, this structure will be used to store luxury au tomobiles. The seemingly insurmountable hurdle that Shockey managed to overcome was erecting the structure on the existing site. While the footprint of the structure is 207 ft 8 in. x 120 ft 5 in. (63.3 x 36.7 m), the structure is being erected by a 450-ton (408 Mg) Leibherr crane, 38 ft (11.6 m) wide from track to track, on a

very tight site — the access point of the deck is 40 ft (12.2 m). The crane was shipped from Ger many to the job site, where it was as sembled over a four-day period. The crane has a 350 ft (110 m) boom to set the project’s 156 pieces of precast con crete, which were manufactured in Shockey’s Winchester, Virginia, facility. It is expected this project will be com pleted before the end of the year. The general contractor for the project is Jack Bays, Inc., of McLean, Virginia. The architect is The J3 Design Collec tive, located in Falls Church, Virginia.
