August 12, 2011 - TRAFFIC ADVISORY - Denver Metro Colorado/CDOT Region 6 - DENVER— Starting Sunday, August 14th and continuing for eight consecutive nights through Monday, August 22nd, crews will demolish the old Stapleton Airport runway service road over I-70, which is located between Havana Street and Quebec Street.

The work is part of the ongoing Central Park Boulevard interchange improvement project.

To begin, on Saturday, August 13^th, a right lane closure will be in effect on westbound I-70 only between Havana Street and Quebec Street from 8 p.m. to 7 a.m. the next morning to allow crews to begin utility removals and work on removing the bridge span that isn’t over traffic.

To complete the work, there will be various full closures of I-70 between Quebec Street and Havana Street from August 14^th through August 22^nd, weather permitting:

Eastbound I-70 between Quebec Street and Havana Street:

o August 14^th through August 18^th: Full closure will take place from 10 p.m. to 5 a.m. each night.

o August 19^th: Full closure will take place from 11 p.m. to 7 a.m.

o August 20^th: Full closure will take place from 9 p.m. to 7 a.m.

o August 21^st: Full closure will take place from 10 p.m. to 5 a.m.

Westbound I-70 between Havana Street and Quebec Street:

o August 14^th through August 18^th: Full closure will take place from 11:30 p.m. to 5 a.m. each night

o August 20^th: Full closure will take place from 9 p.m. to 7 a.m.

During all of the full closures of I-70, motorists will be detoured via the on and off ramps at the new diamond interchange at Central Park Boulevard.

In addition, one lane of eastbound I-270 between Quebec Street and I-70 will be closed from 8 p.m. to 5 a.m., Sunday through Thursday, August 14^th – 18^th, from 8 p.m. to 7 a.m., Friday and Saturday, August 19^th and 20^th, and from 9 p.m. to 5 a.m. Sunday, August 21^st.

Major delays are possible and alternate routes are strongly advised. CDOT would like to remind motorists to plan ahead, obey all construction signs and flaggers and to “Slow for the Cone Zone.” Most fines for infractions that occur in the work zone will be doubled.

This interchange improvement project constructs a full interchange at I-70 and Central Park Boulevard, which is located between Havana Street and Quebec Street. The project will construct all ramps connecting Central Park Boulevard with eastbound and westbound I-70 and I-270.

SEMA Construction, Inc. is the contractor of this $47.2 million project being funded through the American Recovery and Reinvestment Act (ARRA) as well as the City and County of Denver voter-approved Better Denver Bonds. The City and County is providing primary construction oversight, with cooperation and additional oversight by the Colorado Department of Transportation. The interchange will be open to traffic by early October 2011.
