To complete the work, the following lane closures will be in place, weather permitting:

Tonight, March 29th, one lane of northbound and southbound I-25 between I-70 and Speer Boulevard will be closed starting at 7 p.m. with a second lane closing at 9 p.m. All lanes of I-25 will close at 11 p.m. and reopen by 9 a.m. on Saturday.  In addition, 15th Street over I-25 will be closed from 10 p.m. tonight until 8 a.m. on Saturday.

On Sunday, March 31st, one lane of northbound and southbound I-25 between I-70 and Speer Boulevard will be closed starting at 7 p.m. with a second lane closing at 9 p.m. All lanes of I-25 will close at 11 p.m. and reopen by 5:30 a.m. on Monday. In addition, 15th Street over I-25 will be closed from 10 p.m. Sunday until 5:30 a.m. on Monday.

The following detour routes will be place over the weekend. Major delays are possible and alternate routes are strongly advised.

Southbound I-25: Exit onto westbound I-70 and take I-70 to Federal Boulevard. Travel south on Federal Boulevard to Speer Boulevard and then south on Speer Boulevard to I-25.

Northbound I-25: Exit onto northbound Speer Boulevard and take Speer Boulevard to Federal Boulevard. Then travel north on Federal Boulevard to I-70. Take I-70 east to I-25.

Uniform traffic control will be in place throughout the detour routes to help guide motorists and to monitor the flow of traffic during the closure. CDOT would like to remind motorists to obey all construction signs and flaggers and to “Slow for the Cone Zone.”

Additional work will take place during the following week for bridge deck construction Monday, April 1st through Thursday, April 5th:

 

  • One lane of northbound and southbound I-25 between I-70 and Speer Boulevard will be closed starting at 7 p.m. with a second lane closing at 9 p.m. and a third lane closing at 11 p.m. each night.  All lanes will reopen by 5:30 a.m. the next morning.
  • The ramp from westbound Speer Boulevard to northbound I-25 and the ramp from southbound I-25 to 20th Street will be closed from 11 p.m. to 5:30 a.m. each night.

 

The girder installation is part of a safety and mobility project on I-25 between approximately 20th Street and Speer Boulevard that replaces the 15th Street bridge over I-25 and adds auxiliary lanes on southbound I-25 just south of 20th Street to just south of Speer Boulevard to help eliminate the weaving at the on and off-ramps on I-25.

In addition, various vehicle, pedestrian and bicycle improvements will be made on Central Street, including constructing of a 10-foot bicycle/pedestrian path from 16th Street to 20th Street and adding additional on-street parking on the west side of Central Street north of 17th Street. The City and County of Denver is funding the improvements along Central Street.

Hamon Contractors, Inc. is the contractor for this $11.7 million project that will continue through late 2013 or early 2014.
