Arrowhead Highway 6 Safe Crossing Project

The Arrowhead Metro District has been developing a plan to address the need for a safe crossing of US Highway 6 for pedestrians and bicyclists.

Two priorities have been identified: safe crossing for pedestrians and bikers, and, in anticipation of higher volumes of high-speed traffic in the near and long term future, safer ingress and egress of cars into and out of the main Arrowhead entrance.

CDOT has advised that a roundabout is the only option that solves both priorities.

After several years of research, investigation, discussion and planning, the Metro District is moving forward with construction of a roundabout at the main Arrowhead entrance, equipped with at-grade crossings and flashing lights in the low-speed areas entering and exiting the roundabout.

Project information, progress and updates will be posted on this page. Occasional communication will also be sent to homeowners via email.

See below for details.

Main Entrance/Exit Widening 

In addition to building the roundabout, the main gate entrance and exit lanes will be widened from Hwy 6 to the Main Gatehouse. This will allow for 2 full entrance lanes on the entrance side, and a dedicated pedestrian lane on the exit side.

8/23/2024 Update

The project construction moved to the south side of Highway 6 on Tuesday, August 20th. The plan that was presented at the Metro District Town Hall, that included no closure of the Arrowhead main gate, has been changed by CDOT. While entry and exit at the main gate was to be available, the revised plan allows for entry only at the main gate through the remainder of the project. Exit from the south side of Arrowhead is via the East and West gates.

The construction work taking place through Wednesday, August 28th, will be installation of all of the deep and shallow storm drains. That will be followed by excavation for the concrete curbs and islands.

The project is scheduled to be complete by mid-October.

8/19/2024 Update

Beginning Tuesday afternoon, August 20th, the Highway 6 Safe Crossing Project traffic pattern will shift to the north side of Highway 6. Click HERE to see a detailed outline of the lane shift.

There will be no changes for entrance into the south side of Arrowhead, however exit from the south side of Arrowhead will only be permitted through the East and West Gates. There will be detour signs in the community, primarily guiding people to the East Gate exit. Click HERE to see a detailed east side detour map.

There will be access to the Main Gatehouse via the exit lane on Arrowhead Drive, up to the gate only. There will be a hard closure in the exit lane, just past the Main Gatehouse, and exit will not be permitted at this location.

08/16/2024 Update

Saturday, August 17th - Asphalting on the north side of the project will take place.

Monday, August 19th - Restriping of the road and final cleanup of the north side will take place.

Tuesday, August 20th - The south side barriers will be rearranged in preparation for a new traffic pattern that will begin on either Tuesday, August 20th, or Wednesday, August 21st.

Information about the new traffic pattern will be communicated as soon as it is available.

08/07/2024 Update

On the north side of the project, all concrete curbing and sidewalks have been completed. Asphalt and road base is being installed to prepare for laying asphalt during the week of August 12th. A traffic pattern change, when construction moves to the south side of Highway 6, is now anticipated during the week of August 19th.

07/31/2024 Update

Storm drain installment is complete. Paving and framing for concrete work on the north side of the project is in process. Installation of lamp post bases has begun. A traffic pattern change is anticipated during the week of August 12th. Details of the traffic pattern change will be communicated as they become available.

07/23/2024 Update

The project is on schedule with anticipated completion by the end of September 2024. The recreation path has been relocated to it’s permanent location and is open for use. Storm drain installment continues and the roundabout area has been excavated. During the first week of August, construction will shift to the south side of Highway 6. Details of the resulting traffic pattern change will be communicated as they become available.

07/01/2024 Update

Storm Drain installment will continue this week. Milling the asphalt should start tomorrow, Tuesday, and run into Wednesday. The recreation path has been detoured for realignment. Per CDOT there will be no construction Thursday thru Sunday for the Holiday.

06/24/2024 Update

The project crew is in the process of creating a temporary detour for the recreation path. They will be working quickly to re-establish the regular path.

06/13/2024 Update

CDOT has issued to the AMD, the official Notice to Proceed (NTP) as of this week. This means they have approved the construction plans, environmental plans, road right of way and allowed for a pre-construction meeting, which occurred this week. You will start seeing the barricades set up and construction commence next Monday, 06/17/2024. The development timeline is looking promising for completion mid September barring any unforeseen delays.
