Lefthand Canyon construction update for March 16, 2016

Hello Lefthand Canyon Construction Listserv Member -

I hope all is well. Construction continues to move forward in Lefthand Canyon between James Canyon Drive and Olde Stage Road. Everything remains on schedule to finish this phase of work prior to Memorial Day in May. As you may have seen if you traveled through the work area, construction activities have moved beyond the James Canyon to Olde Stage zone in both directions. This will continue as Central Federal Lands secures landowner permissions to conduct construction-related activity on properties needed to complete the planned work.

For construction activity out of the main closure zone, the contractor has the ability to hold traffic for up-to 30-minutes at a time in order to safely conduct operations. The contractor understands the inconvenience this might cause for the daily lives of area residents, so they're going to do their best to maintain at least one lane of travel that will be guided by traffic control personnel. Delays this week and next should be short (up to five minutes maximum), but they will likely get longer the week of March 28, specifically in the area below Olde Stage Road. More information will be provided as details are finalized and I'll do my best to provide as much advance notice of any delay as I can.

Current Construction Activities

Structures Inc. has begun work on another bridge, bringing the total of active bridge construction sites to three. They're making quick work of the two they started in January and plan to add girders to both of them in early April. Once girders are set, the decks will be poured and guardrails will be installed, with paving and striping to finish the bridge.

MC Donegan continues work on creating pioneer roads into the hillsides in order to prepare for major excavation work. All of their work to-date has gone to plans and you can see the tremendous progress they've made since the job began.

Kelley Trucking Inc. (KTI) has their rock hauling work cut out for them following MC Donegan, but they're doing an amazing job moving hundreds of thousands of pounds of rock and soil after it has been loosened from the hillside. All of the material they haul away is reused somewhere else in the project area to build up the road, create stream-side embankments and armoring using rip rap, and to fill in low spots throughout the canyon. KTI is also working on installing numerous concrete culverts under the roadway that will carry water from the hillside to the creek. To-date, they've installed 12, which is just over half of what is called for in phase I.

Crews have done all of this work and have had to survive a zombie invasion! Only kidding! Someone decided to have a little fun with one of our variable messagr boards last weekend and changed the sign to read, "Caution. Zombies Ahead." Definitely amusing, but not exactly helpful for getting the project completed on time. Please do not touch construction equipment or materials that have been staged in the area. The last thing we want is for someone to get hurt doing something they shouldn't or for a piece of equipment to get damaged, which might slow down the work.

I'd like to thank you all again for your time, patience and understanding while we work in Lefthand Canyon. While you may not play an active role in the physical work, we really couldn't have gotten this far without you. Please let me know if I can be of any assistance at any time.

Have a good evening.
