Crews have completed all of the concrete repairs on eastbound and westbound C-470 between I-25 and Santa Fe Drive and asphalt resurfacing is just beginning. Since temperatures are not yet warm enough for paving during the overnight hours, crews will continue to work on weekends.

“With the concrete work complete, we will micro-surface C-470, which seals the concrete and levels the pavement,” said CDOT Project Engineer Doug Liane. “Once that work is complete, we will resurface both directions of C-470 in asphalt for a smooth driving surface.”

Concrete repairs on C-470 between I-25 and Santa Fe Drive will once again take place this weekend and next week. This weekend, crews will work from 8 p.m. on Friday, April 9th to 5 a.m. on Monday, April 12th, weather permitting. During this time, closures will be in place on C-470 and major delays are expected.

CDOT Press Release

This weekend and next week, the Colorado Department of Transportation (CDOT) will continue concrete repairs on eastbound C-470 between I-25 and Santa Fe Drive and conduct some minor work on westbound C-470.

This weekend, crews will work from 8 p.m. on Friday, October 23rd to 5 a.m. on Monday, October 26th. During this time, the following closures will be in place on C-470 and major delays are expected:

Eastbound C-470 between Broadway and Colorado Boulevard- The left lane of eastbound C-470 will be closed from 8 p.m. Friday to 5 a.m. Monday. Major delays are expected and alternate routes are strongly advised.

Westbound C-470 between University Boulevard and Lucent Boulevard - The left lane of westbound C-470 will be closed from 5 a.m. to 1 p.m. on Sunday only.

Since the concrete repairs require crews to place new concrete, there is about a 10 to 12-hour timeframe in which the concrete has to cure. During this time, the lane closure will remain in place but crews will not be visibly working. This is a necessary process for concrete replacement to ensure the pavement is of high quality and can withstand the heavy traffic C-470 handles. Once the concrete cures, crews will stripe and conduct some other minor work before reopening eastbound C-470.

In addition, there will be various closures Monday, October 26th through Thursday, October 29th:

Monday, October 26th and Tuesday, October 27th: One lane of westbound C-470 between Wadsworth Boulevard and Ken Caryl Avenue will be closed from 8 a.m. to 3:30 p.m. In the evenings, one lane of eastbound C-470 between Quebec Street and Yosemite Street will be closed from 8 p.m. to 5:30 a.m. The ramp from Quebec Street to eastbound C-470 will also be closed on Tuesday from 8 p.m. to 5:30 a.m.. Motorists can take County Line Road to Yosemite Street or I-25 as a detour route.

Wednesday, October 28th and Thursday, October 29th: One lane of eastbound C-470 between Broadway and University Boulevard will be closed from 8 p.m. to 5:30 a.m.

CDOT would like to remind motorists to obey all traffic signs and flaggers and to “Slow for the Cone Zone.” Most fines will be doubled if the infraction occurs in the work zone.

Major concrete repairs on the C-470 bike path between I-25 and I-70 are also underway. As a result, a small section of the bike path between West Alameda Parkway and Rooney Road will be closed as well as the section between Quincy Avenue and Belleview Avenue. Bicyclists will be asked to dismount and walk around the construction zone.

This work is part of an American Recovery and Reinvestment Act (ARRA) project. The $32 million project will repair nine miles of C-470 and then pave the entire length in asphalt. Concrete repairs will also be made along 26 miles of the C-470 bike path between I-25 and I-70.

Castle Rock Construction Co. of Centennial, CO is the contractor for this project, which is scheduled to be complete in July 2010.

In all, Colorado will receive more than $400 million from the Recovery Act for transportation projects and $103 million for transit projects.
