Multiple Projects to Cause Delays on I-25 Near Downtown Denver Starting Sunday Night

September 14, 2012 - Denver Metro Area/CDOT Region 6 - Beginning Sunday, September 16th, through Thursday, September 20th, there will be various lane and ramp closures on northbound and southbound I-25 between Colfax Avenue and 23rd Avenue and near 15th Street as part of two ongoing construction projects.

Major delays are expected along this stretch of I-25 and alternate routes are strongly advised.

Motorists can expect the following closures each night Sunday through Thursday, unless otherwise noted:

Southbound I-25 between 23^rd Avenue and 6th Avenue (Sunday, September 16^th, only): One lane of southbound I-25 will be closed at 7 p.m. with a second lane closing at 9 p.m. and a third lane closing at 11 p.m. for barrier and pipe work. All lanes will reopen by 5 a.m. the following morning.
Northbound I-25 between Speer Boulevard and Colfax Avenue: One lane of northbound I-25 will be closed at 7 p.m. with a second lane closing at 9 p.m. and a third lane closing at 11 p.m. for pipe work. All lanes will reopen by 5 a.m. the following morning.
Northbound and Southbound I-25 near 15^th Street: One lane of northbound and southbound I-25 will be closed at 7 p.m. with a second lane closing at 9 p.m. and a third lane closing at 11 p.m. for bridge work. All lanes will reopen by 5 a.m. the following day.
23^rd Avenue to Southbound I-25: The ramp from 23^rd Avenue to southbound I-25 will remain closed until 3:30 p.m. on August 24^th for paving operations. Traffic is being detoured to Mile High Stadium Circle Drive to Colfax Avenue and then to southbound I-25.
Westbound Speer Boulevard to Northbound I-25: The ramp from westbound Speer Boulevard to northbound I-25 will be closed from 11 p.m. to 5:30 a.m. the following day for bridge work. A detour route will be posted.
20^th Street to Southbound I-25: The ramp from 20^th Street to southbound I-25 will be closed from 7 p.m. to 5:30 a.m. the following day for retaining wall work. A detour route will be posted.

CDOT reminds motorists to obey all construction signs and flaggers and to “Slow for the Cone Zone.” Fines for most infractions that occur in the work zone will be doubled.

The work is part of two ongoing construction projects. The first is a safety and mobility project on I-25 between approximately 20^th Street and Speer Boulevard that replaces the 15^th Street bridge over I-25 and adds auxiliary lanes on southbound I-25 just south of 20^th Street to just south of Speer Boulevard to help eliminate the weaving at the on and off-ramps on I-25. The $11.7 million project will continue through late 2013 or early 2014.

The second project is a bridge replacement project on I-25 between Colfax Avenue and 23rd Avenue. The existing I-25 bridges over the South Platte River were originally constructed in 1951 and are in poor condition. The $16.3 million project is scheduled to be complete by the end of August 2013.
