Hello -

Upper Fourmile Canyon/Wall Street

Longer Work Day and Delays at Mile 10

Starting on Monday morning, right around the 10-mile mark (10000 Fourmile Canyon Drive), CEI will start drilling 10 40-foot deep caissons for a new retaining wall. In order to shorten their duration in this spot, CEI has asked for and been granted longer work hours and longer road closure hours. The road is extremely narrow in this location, so it will be too tight to operate a drill and move cars by the work site at the same time. Extended hours and closures:

• Road closed 8:30 a.m. to 1 p.m.
• Open 1 to 1:30 p.m.
• Road closed 1:30 to 5:30 p.m.

When work begins in this location, CEI will need to use traffic signals in the evening because the road will be reduced to one-lane at all times until work is complete, which the estimate will take between two and three weeks. The other traffic signal that is currently in use will also remain due to the lane reduction, so give yourself a little more time to get down the road and please do not run red lights as this could result in a head-on crash.

Normal Daytime Delays to Continue

CEI will continue the 2-hour closures starting at 8:30 a.m. with 30-minute openings at various locations along the road. At 1 p.m. each day, the entire road will be open from end to end for 30-minutes. I will try to provide more detail on exact locations, but they are a moving target right now. CEI has been trying to move people around their closure locations as they can, so there is a chance you can sneak by, but know that the road will always be open for 30-minutes at 10:30 a.m. and 1 p.m. each day. The reason the road is closed can be seen in the photo below. We're installing culverts under the road itself and the road is too narrow to complete the install and keep a lane open.

Gold Run/Salina

A majority of the current work continues to focus on culverts above the schoolhouse and on the retaining wall across from the Church (photo below). Grading crews continue to bring the road to its intended elevations. Road base will be delivered the week of June 25. The road will be ready for paving after the week of July 2, but the paving subcontractor may not be able to pave until the week of July 16 due to other commitments. We'll get the paving crew up there ASAP. Expect delays of 5 to 10 minutes through Gold Run, but they could range, infrequently, up to 15-minutes. 

Logan Mill

The bridge deck was just poured at Logan Mill (photo below). You can also see crews are hard at work on the retaining wall just below the bridge. In two weeks, they plan on starting the wall just above the bridge. In order to complete this work, Fourmile Canyon Drive will be reduced to one-lane 24-hours a day, seven days a week. A temporary traffic signal will be installed in order to move people safely around the lane closure. The signal will be equipped with optical sensors that will detect approaching cars to help shorten the wait time. Please do not run red lights. Not only is this dangerous, but it also causes the signal to reset and go into timed- mode for a few cycles while it resets, which makes the wait longer for the next people coming along. 

Lower Fourmile Canyon Drive

Bids for construction services have been received and opened. We are currently analyzing all bids and will soon make a final decision on who will complete the project. I'll provide more information as soon as everything is determined. We'll host a public meeting with the contractor in July or August so that you can meet the team and we can go through all constructions specifics, including anticipated travel delays.  

Daytime Weekday Recreational Cycling Restrictions Remain in Effect

Please refrain from cycling in the canyon from 8 a.m. to 4:30 p.m., Monday through Friday. As you can see from the project updates above, there's a lot of work going on, which means a lot of large trucks and equipment heading up and down the road each day. The last thing we want is to see someone get hurt.

Thank you for your time, patience, and understanding.

Let me know if you have questions.

Have a good day.

Sincerely,

Andrew
