Lefthand Canyon construction update

Hello -

Here's what you can expect to see and experience on Lefthand Canyon Drive from Monday, Sept. 26 through Friday, Sept. 30.

Mile 1.3

Excavation work will continue in this area throughout the week. In order to keep travelers safe from falling rock the road will need to be closed for up to one hour at a time. Kelley Trucking, Inc. (KTI) will ensure that the road is open at this point every hour on the hour between 7 a.m. and 5 p.m., Monday through Friday. There is no work on the weekend.

Olde Stage Intersection

The large pile of rock and dirt will continue to be sorted for usable material. There will continue to be short delays at this spot when trucks are being loaded with material and hauled away.

Paving Operations

Paving will resume on Monday, Sept. 26 and will continue through the week. Work will begin at "the cut" just east of James Canyon Drive. The plan is to completely finish paving this section before moving farther west. Work at the cut should take 2 - 3 days as the road will need to receive both the bottom and top layers of asphalt.

After the cut is paved, operations will move to the bridge between James Canyon and Lee Hill and will proceed west.

KTI will do their best to keep delays as short as possible and will use flaggers to move people safely through the work zone, but as you've seen, there may be some longer waits.


Blasting/excavation work will likely resume in the area east of Glendale Gulch on Tuesday and will continue through the week. KTI would like to conduct one blast in the morning and one in the afternoon. The blasts in this area have been relatively small and the road is generally only closed for 30-45 minutes to safely conduct operations and to clear debris. Blasts are typically scheduled for 9 a.m. and 1 p.m.

Guardrail, Striping, and Signing

As you may have seen, guardrails, roadway striping and signage work is well underway and will continue throughout the week. A flagger may be used to move people safely around this work when needed and short delays may be observed.

Stream Restoration Begins Sept. 26

On Monday, KTI will begin working with Biohabitats and the United States Forest Service (USFS) on stream restoration operations. A majority of the work will take place near the confluence with James and Left Hand creeks. This work should not impact the traveling public.

Plans call for the cutting of several trees. These trees will be reused in the riparian corridor to create aquatic habitat and mitigate stream flows. In addition to creating better habitat and a healthy ecosystem, work in the stream is also aimed at increasing the roadway's resiliency, by preventing the creek from flowing towards the road and eroding stream banks and undercutting the road itself.

Thank you for your time, patience and understanding. Please let me know if you have any questions, comments, or concerns.

Have a good day.
