Project background

The first stage of the project to began in July 2013. Glenshire Drive was widened to 32 feet, and two 5-foot shoulder-paved bike lanes were added from 900 feet east of the Highland Avenue/Glenshire Drive intersection to the Berkshire Circle/Glenshire Drive. Click here to read more.

The second stage of the project began in July 2014; it involved the installation of a drainage culvert replacement and other work on Glenshire Drive between Donner Pass Road and Olympic Boulevard. Click here to learn more.

TRUCKEE, Calif. — Work to widen, reconstruct and improve portions of Glenshire Drive and Highland Avenue is scheduled to begin next week.

Truckee Town Council on Aug. 11 approved the Glenshire Drive/Highland Avenue Intersection Safety Improvement Project, the third and final phase in a three-year endeavor to overhaul the main road between downtown and the Glenshire subdivision.

The $746,000 project begins Monday and is expected to take about 30 days, with final treatments completed by the expected date of Oct. 15, said Todd Landry, senior engineer with the town.

Funding will come through a federal Highway Safety Improvement Program grant, accounting for about 90 percent of the costs, Landry said, with the remainder coming from the town’s Measure V roadway maintenance fund.

Prior to council approval, the public was given an opportunity to voice concerns.

“If anything, people’s only real criticism was why the project wasn’t started last year,” Landry said.

To that, Landry noted a lengthy process applying for the HSIP grant.

“It had a lot to do with the funding source,” Landry said. “… We had to go through a lot more paperwork to satisfy the feds.”

Planned improvements include construction of a short left-turn pocket on Glenshire Drive and widening and reconstruction of Glenshire from approximately 1,000 feet east of Highland to 1,500 feet west of Highland to accommodate bicycle lanes, according to the proposal.

Construction will implement stormwater and erosion control improvements, including upgrading culverts and installing sand inlets deeper to allow for water runoff to mix with sand, Landry added.

The project will also improve the horizontal and vertical slope at the intersection, including flattening the vertical curve along Glenshire just west of Highland and shifting Glenshire farther south to increase driver sight distances, Landry said.

TRAFFIC DELAYS

Landry expects some traffic impacts, and alternating traffic controls with flaggers will likely be implemented through most of the work.

“The cues in the delays should be about five minute delays,” Landry said. “If it gets more than that, planners will have to reassess strategies.”

Those strategies could include the closure of parts of Glenshire as well as crews doing work outside of the planned weekday 7 a.m.-until-dusk shifts.

If Glenshire closes, it would be between Highland and Olympic Boulevard, Landry said, in which case, traffic would be rerouted up Highway 80 east to the Hirschdale Road exit.

It’s unlikely that type of closure would happen during the normal work week, and would only occur on a Saturday if it happens at all, Landry said.

Should a closure be required, prior notice would be issued ahead of time.

“We would use signs posted at Glenshire, letting people know the dates and the times of the closure,” Landry said. “If we gave people enough notice that it was happening on a weekend, it would give folks the notice to use Hirschdale.”

Like River Street and Donner Pass Road and Brockway roads, Glenshire’s improvements are considered with a 15-year life span, including general maintenance, based on frequency of traffic and the average speed cars travel upon them, according to the town.

Landry noted due to the high frequency of traffic and the average rate of speed being around 50 mph, it is important the road be well maintained as the town continues to grow.

“It’s one of our backbone roads, that’s for sure,” Landry said.
