Westbound Lincoln Avenue on-ramp to southbound I-25 weekend closure starts at 10 p.m. on Friday

January 19, 2016 - Metro Denver/CDOT Region 1 - Northbound I-25 full highway closure tomorrow night.

LONE TREE – Paving operations require a full closure of the westbound Lincoln Avenue loop on-ramp to southbound Interstate 25 beginning on Friday, Jan. 22 at 10 p.m. The ramp will reopen by Monday, Jan. 25 at 5:30 a.m. in time for the morning commute. Construction of this ramp and the eastbound Lincoln Avenue on-ramp to southbound I-25 are the last major highway paving elements of the I-25 widening project. All work is weather-permitting and subject to change.

A signed detour will be provided during the ramp closure. The detour uses westbound Lincoln Avenue to southbound RidgeGate Parkway (left) to re-route traffic onto southbound I-25 at the RidgeGate Parkway interchange. Visit www.codot.gov/projects/i25lanebalance for more information on this closure including a detour map.

As a reminder, overhead sign bridge installation requires the full closure of northbound I-25 at Colorado Highway 470 / E-470 tomorrow, Jan. 20, starting at 11 p.m. All lanes will reopen by 5:30 a.m. Thursday, in time for the morning commute. The northbound I-25 closure at Lincoln Avenue scheduled for Jan. 21 has been cancelled. Additional highway closures will be announced in the coming weeks.

Wednesday, Jan. 20: Northbound I-25 will be closed at C-470 / E-470 (11 p.m. to 5:30 a.m.)

To detour around this closure, through traffic will use the off-ramp at Lincoln Avenue (exit 193), travel east (right) on Lincoln Avenue, head north (left) on Peoria Street, and enter westbound E-470 to access the on-ramp to northbound I-25. This detour route was used by the project in September 2014 when the old sign bridges were removed. A detour map is available on the project website (www.codot.gov/projects/i25lanebalance).

The northbound I-25 ramps to C-470 and E-470 will remain open during this closure. All remaining northbound traffic must exit onto either C-470 or E-470 (exit 194). Northbound I-25 motorists will be detoured onto E-470 to the Peoria Street off-ramp. Traffic will then be directed to enter westbound E-470 to access the on-ramp to northbound I-25.

E-470 tolls will not be collected along the detour route while the full closure is in place. Southbound I-25 will remain open.

Sign bridge installation is part of the I-25 widening project, which is nearing completion. Final median barrier and lighting installation will continue over the next several weeks. In February, there will be an overnight closure of southbound I-25 while an overhead sign structure is put in place on the west side of the highway.


The I-25 Widening Project adds an additional lane in each direction on I-25 from Lincoln Avenue to County Line Road, resulting in four lanes in each direction south of the C-470 / E-470 interchange. In addition to expanding capacity on I-25, crews have replaced asphalt with concrete to better match the I-25 corridor. This project improves traffic patterns from and to all affected ramps as well as provides new pedestrian connections. Funded by CDOT, Douglas County, City of Lone Tree and the Denver Regional Council of Governments (DRCOG), this $32 million project is ahead of schedule with anticipated substantial completion in early 2016.
