At a recent Public Meeting, officials from CDOT shared details regarding construction happening on I-25 and the impacts on the Timnath community. See below for the current schedule. Please keep in mind that this is subject to change.

April 19 – May 7
Work on Harmony Road at the I-25 overpass to widen the pavement on the west side and create a 3rd westbound lane over the interstate. Single lane closures and intermittent I-25 on- and off-ramp closures will take place from 9 p.m. to 5 a.m., Monday through Friday.

First week of May (currently scheduled for May 6)
Full closure of Harmony Road between the interstate ramps from 9 p.m. – 5 a.m.  This closure allows CDOT to restripe the bridge and install temporary traffic signals at the southbound ramp.  Traffic will be detoured via the access ramps to Prospect Road if westbound and Hwy 392 if eastbound to cross the interstate.

May 10
Permanent closure of the frontage road from Ketcher Road to the Connell asphalt plant entrance.  Access to the Costco area will be from Harmony Road only until Weitzel is extended.

September 2021 – April 2022
Closure of the Ketcher bridge over I-25 for reconstruction.
