Much anticipated I-25 Gap Lane Project brings FULL weekend closures of I-25, beginning August 8 But WAIT…There’s More!!!

August 2, 2014 - Metro Denver Colorado/CDOT Region 1 - But WAIT…There’s More!!!

DENVER – The Colorado Department of Transportation (CDOT) is moving forward with the I-25 Gap Lane Project to deliver a much-needed improvement to northbound I-25 between Santa Fe Drive and the US 6 interchange. Essentially, crews will create a fourth thru lane on northbound I-25 between Santa Fe Drive and US 6.

Adding a fourth lane in this area requires a significant amount of work over the weekend of Aug. 8-11. To minimize inconvenience to the traveling public, crews will complete this work in two phases, enabling the highway to remain open during the day on Saturday.

The highway will initially close Friday, Aug. 8, at 10 p.m. and remain closed until 8 a.m. Saturday. The roadway will remain open throughout the day on Saturday. Then, Saturday night at 10 p.m., both directions of I-25 will close again, reopening by 5 a.m. Monday. Crews will begin setting closures approximately one hour prior to the full closures being implemented.

TRAVEL IMPACTS: Local detour routes for the full I-25 closure include the following:

Northbound I-25 will detour to northbound Santa Fe Drive, continue north to 8th Avenue, west on 8th Avenue to Kalamath Street, and south on Kalamath Street to westbound US 6 to reconnect with northbound I-25.

Southbound I-25 will detour west on US 6 to Federal Boulevard, south on Federal Boulevard to 5th Avenue to merge onto eastbound US 6, and east on US 6 to reconnect with southbound I-25. There could also be delays along eastbound US 6 near I-25 with additional traffic following this detour route.

Northbound Santa Fe Drive: In conjunction with this closure, northbound Santa Fe Drive will close just south of I-25 over the weekend, with traffic detoured on Mississippi Avenue to northbound Broadway and eventually Lincoln Street. Access to businesses along Santa Fe Drive will be available via Alameda Avenue. Detour signage will guide commuters through the area.

During these full closures of I-25, crews will restripe and shift northbound lanes and repave the highway, consolidating over one month of work into one weekend.

“We can’t emphasize this strongly enough: avoid this area of I-25 during these closures if at all possible,” said Kevin Sullivan, CDOT Project Director. “We expect extensive backups, prolonged travel delays and excessive traffic congestion if traffic numbers reach normal Sunday volumes.”

CDOT implores regional through traffic to avoid the area altogether by using I-225, I-70, US 285, C-470,

E-470 or any other alternate route. CDOT and Kraemer and Sons, the contractor for the US 6 Bridges Design Build Project will be providing courtesy patrol free of charge to motorists in need along the outlines of this closure and throughout the boundaries of the project.

“RTD’s light rail service is another option if you need to get downtown,” Sullivan continued. “Realistically, the best bet is to cross I-25 off the list for that weekend and use alternative modes of transportation or alternate routes.”

While crews will narrow all lanes to 11 feet and shoulders in both directions of I-25 to make room for this additional northbound lane, the benefits outweigh this tradeoff. When I-25 reopens Monday morning, northbound drivers will be able to use this additional lane to help improve traffic flow. Although this will not eliminate traffic congestion in this area, it will certainly be an improvement and will increase mobility through this heavily traveled stretch of highway.

That said, due to ongoing US 6 Bridges Project work, drivers will not realize the full benefits of the I-25 Gap Lane Project until the completion of the northbound I-25 off-ramp flyover bridge to westbound US 6, currently scheduled for early 2015.

The I-25 Gap Lane Project only provides a temporary fix to traffic congestion in this area, as the long-term solution will not come until funding is available to make permanent improvements to I-25 between Alameda and US 6.

But WAIT…There’s more!

The I-25 North Express Lanes Project which is adding one HOV/tolled Express Lane in each direction of I-25 beginning at 120th Avenue that will connect with the existing I-25 Express Lanes system at US 36 and I-25 is in the midst of a 50 day work period that will accommodate the lowering of I-25 pavement underneath the 88th Avenue bridge. This work will improve the vertical clearance on the roadway under the 88th Avenue bridge by approximately one foot.

A single lane closure of the innermost lane of southbound I-25 between 84th Avenue and Thornton Parkway was originally scheduled for this weekend. Due to the rain over the past week, work had to be pushed back and the closure has been rescheduled for the weekend of August 8. Due to the aggressive scheduling for this portion of the project is important that this work be completed quickly. Delaying the work by only one weekend is crucial to keep the project on track for completion.

“This portion of the I-25 North Express Lanes project has been reduced to 50 days from the original 100 days in order to minimize the impact to the traveling public,” Andy Stratton, Project Engineer for the I-25 North Express Lanes said. “In order for us to remain on schedule we must move forward with this closure as quickly as possible despite weather delays.”

This work will be highly impactful to motorists traveling southbound I-25 in this area and with the full closure of I-25 only a few miles south that same weekend CDOT encourages motorists to avoid I-25 throughout the Denver metro area and to use alternate routes throughout this entire weekend.
