Michael Baker Jr., Inc., an engineering unit of Michael Baker Corporation has been selected as the lead engineering team on three design/build bridge replacement/rehabilitation projects awarded by the Utah Department of Transportation (UDOT). The total construction value of the contracts is approximately $13 million, while Baker’s bridge and highway design fee is $1.1 million. All three projects are being funded under the American Recovery and Reinvestment Act (ARRA).
The three projects include six deck replacements on Interstate 15 bridges near Payson, the replacement of Interstate 80 over Echo Junction bridges in Summit County, and the replacement of Interstate 80 over 2300 East bridges in Salt Lake City.
All three projects will employ Accelerated Bridge Construction (ABC) methods which involve precast bridge design elements and construction of the new structure near the existing bridge. The Echo Junction and 2300 East bridges will be replaced by sliding the new bridges into place over a 16-hour period, while the Payson deck replacements will use precast deck panels and replace the decks one half at a time while keeping the other half open. Baker will team with Ralph L. Wadsworth Construction on all three projects, with the work to be completed by November 2009.
