In September, crews completed the asphalt overlay on the E-470 bridges over I-70, 19th Ave., Colfax Ave. and the on and off ramps to the I-70 interchange. Crews also completed the final painting and structure work for these bridges.
Substructure was also completed on the E-470 bridges over Smith Rd. and Union Pacific Railroad with girders being erected in September.
Relocated E-470 Ramps
Subgrade and asphalt paving was completed for the relocated off ramp from E-470 to Quincy Ave. via Gun Club Rd. Next, crews will move on to the final asphalt finishing and painting for the off ramp, and will begin the subgrade paving for the relocated on ramp.
The final asphalt surfacing was completed on northbound and southbound E-470 between 6th Pkwy./Stephen D. Hogan Pkwy. and the southbound off ramp to the I-70 interchange. Next, crews will move on the final striping of the third lanes in both directions.
In September, crews worked on eight water quality ponds located along the roadway. These ponds are part of a larger stormwater drainage system and are expected to reach completion in October.
High Plains Trail
This past month crews continued to tie areas of the trail together with paving, and placed barrier walls to separate vehicle traffic from trail traffic at State Highway 30 and Hampden Ave.
