• 84th Avenue over I-25: This project replaces the 84th Avenue bridge over I-25, originally constructed in 1959 and in poor condition. The new bridge will be wider to accommodate an additional left turn lane from eastbound 84th Avenue to northbound I-25 as well as 10-ft sidewalks on each side of the bridge. The $8-million Bridge Enterprise project will be complete by the end of September.

• I-76 over the South Platte River: This project replaces the eastbound and westbound I-76 bridges over the South Platte River, between York Street and State Highway 224, with one structure. The existing bridges were originally constructed in 1967 and are in poor condition. The new structure will be slightly wider to accommodate wider shoulders. The on-ramp from S.H. 224 to westbound I-76 will be extended across the bridge to allow more time to merge onto the interstate. The $10.5-million Bridge Enterprise project will continue through June.

• I-70 over Sand Creek: This $8-million Bridge Enterprise project will replace the eastbound and westbound I-70 bridges over Sand Creek, between Quebec Street and I-270, with one bridge. The existing eastbound structure was originally constructed in 1960 and the westbound structure was constructed in 1964, and both bridges are in poor condition. The replacement will accommodate longer acceleration and deceleration lanes from Quebec Street to I-70, which will improve safety for motorists entering and exiting the highway. The project will continue through June.

• U.S. 6 (6th Avenue) over Sheridan Boulevard (S.H. 95):  Replaces the 6th Avenue bridge over Sheridan Boulevard, originally constructed in 1961 and in poor condition. Drainage and lighting improvements will also be made including upgrading some traffic signals. The medians north and south of the bridge will be modified to increase the length of the left turn lane, which will help the flow of mainline traffic on Sheridan. The $8.8-million Bridge Enterprise project will continue through August 2013.

• Federal Boulevard over Colfax Avenue: The $5.1-million Bridge Enterprise project replaces the Federal Boulevard bridge over Colfax Avenue with one that is wider to accommodate 8-ft sidewalks on each side of the bridge. The existing bridge was originally constructed in 1960 and is in poor condition. The project will continue through February 2013.

• I-225 at Colfax Avenue (Phases 2 & 3): The $11-million project combines the final two phases to complete this interchange improvement project. The southbound I-225 ramp from 17th Place will be constructed, and the west side of the I-225 bridge over Colfax Avenue will be widened to accommodate the ramp. The northbound I-225 on-ramp at Colfax Avenue will be reconstructed to provide an elevated collector-distributor road between Colfax Avenue and 17th Place. The project will continue through February 2013.
