As you may have seen, one set of traffic signals has been removed from the northern section of the project area. This signal will be put back into use when crews begin to excavate the retaining wall site at the junction, which is anticipated to begin the week of Nov. 19. Before that happens, Lawrence Construction should be able to greatly reduce the length of the work zone where the remaining signal is currently located, which will shorten the wait time for that light.

Today, Lawrence started installing the minor culverts under the roadway. This work will be completed using flaggers during working hours. Fourmile will be returned to two-lanes in these locations at the end of the day and over the weekend. This work is anticipated to continue into December.

Construction continues at the two retaining wall sites located just north of Logan Mill Road. Activity at these walls will continue for several more weeks as multiple loads of concrete are applied before the walls receive their stone veneer. Stone veneer crews will move back to the north zone to start on a recently completed wall starting tomorrow.

Remaining work in the north section, in addition to the minor culverts, retaining wall, and stone veneer, also includes two large culvert structures, paving, guardrail installation, and landscaping/revegetation. Culvert and retaining wall construction and veneer applications can be completed in cold weather, but paving and revegetation will require consistently warmer temperatures.

Work on the stone veneer on the walls in the south section should wrap up tomorrow. Crews will then begin restoring the creek areas behind the walls in this stretch. They anticipate stream restoration will take approximately two weeks.

Work that remains in the south section includes final paving, guardrail installation, and landscaping/revegetation. This work will most likely take place next spring when consistently warmer temperatures return and the ground is more suitable for paving and planting.

After the walls and culverts are completed in the north section, construction is likely to be suspended. We are currently working with the contractor on a plan to maintain two-lanes of travel throughout the canyon while we wait for warm weather to return in order to complete the remaining pieces of the project.

I absolutely understand the fatigue and frustration residents must feel with ongoing work. We are pushing our team to work harder and to keep moving as quickly and safely as possible towards completion. None of the flood recovery-related projects in Fourmile have been easy for our contractors and project neighbors, and this one has been no exception. Mountain corridors are tough places to work, but we'll keep coming back until all is done and done right. I'll share our longer-term plan for completion of the entire project as soon as it has been finalized.

Thank you for your continued time, patience, and understanding. Please let me know if you have questions.

Have a good day.
