November, 2019 Weekend Traffic Advisory 11-8-19
Great progress is being made on E-470 Road Widening Project from Quincy Avenue to I-70! In October, the following project milestones were completed.
- All 12 girders were set on the E-470 northbound Coal Creek bridge. This marks the second set of girders installed as part of the 14 bridges scheduled to be widened as part of the project.
- The first paving also took place on the project from SH30 to Quincy along southbound E-470. Paving activities will be ongoing as crews work to open a third lane on southbound E-470 from Jewell to Quincy Avenue by the end of 2019.
- Critical toll system work was completed at Toll Plaza B for southbound E-470.
Each girder weighs approximately 130,000 pounds and is close to 130 feet long.
Approximately 22 thousand tons of asphalt have been placed on the project to date.
Upcoming November Construction Activities
Please be advised all work is schedule and weather dependent. The following activities are planned for November on the E-470 Road Widening Project.
Now that the girders have been set on the Coal Creek bridges, crews have begun working on the bridge decks. The next girder erections are planned for the Colfax and Ramp B bridges. All substructure work will be complete ahead of early December girders placement for these bridges in[SM1] November. Girder installations are planned to minimize impacts to the traveling public and will take place during nighttime hours or weekends. One lane of travel along E-470 mainline will remain open at all times; however, traffic will be paced while the large girders are removed from the truck by a crane and placed on the bridge structure. Exact dates and times will be advertised via our message board and social media channels. Traffic control will be on-site for the safety of the traveling public.
I-70 Bridge Activities
East and West of E-470, crews will begin re-striping the I-70 work zone for approximately .25 miles under the E-470 Bridges. This work is necessary to support the upcoming bridge widenings and associated I-70 median work. Motorists should expect single lane closures in this area from 6 p.m. to 6 a.m. along I-70, each night in early November.
Coal Creek Bridge Deck Pour
In late November crews will pour the concrete deck on southbound E-470 at the southbound Coal Creek bridge. This will facilitate construction of southbound traffic into a third lane by the end of 2020.
Upcoming Ramp Activities
Motorists should expect minimal impacts at the E-470 on and off-ramps to Quincy Avenue this month. Crews will be creating a ramp detour and reducing the size of the existing ramp lanes to facilitate construction of the third lane of southbound E-470 this year. Please watch for additional activities in this area.
