Caltrans outlines I-80 work
During the next four years, Caltrans plans significant work along Interstate 80 in and around Truckee, an official told town council Thursday.
Caltrans Senior Transportation Engineer Karl Dreher presented to council an overview of upcoming Interstate 80 projects which will affect the flow of traffic into and around Truckee in upcoming years.
“Our goal here is to rehabilitate Interstate 80 from Placer County to the state line,” Dreher said. “This will include much more than putting in paving.”
The scheduled work will bring the 40-year-old interstate up to current standards, Dreher said, explaining that usually a roadway is only given an estimated 20-year life-span.
Caltrans has roughly estimated a $950 million cost of road and utility improvements from Roseville to the Nevada state line, Dreher said, which will allow reconstruction and resurfacing of more than 90 miles of interstate.
– The Donner Park Overcrossing, that portion of Donner Pass Road extending across 80 between the agricultural station and the state park, does not meet current vertical standards, Dreher said, and will be replaced just west of the existing structure.
Caltrans will not divert traffic from the interstate at any time during the Donner Park Overcrossing project, and at all times during construction pedestrians and bicyclists will be accompanied across the span.
The project is slated to begin next spring at an estimated cost of $1.5 million. Occasional ramp closures are expected and a one-night interstate closure will be scheduled for demolition of the existing structure.
Dreher said Caltrans has budgeted $65,000 to landscape the sand collection area just west of the current overcrossing and is actively seeking a new location for sand collection.
– The Trout Creek Undercrossing project is scheduled to coincide with the Highway 267 bypass construction project and will replace the Interstate 80 Trout Creek Bridge spanning Bridge Street. A cement median barrier will also be added at this site. Dreher said two lanes of interstate traffic will remain open at all peak times during the project’s completion and Caltrans does not anticipate closing Bridge Street at any time.
This project will also begin next spring and is scheduled as a two-year project.
– The West Boca, Boca and Floriston project will cost in excess of $90 million and will result in an 18-month closure of the Floriston off-ramps.
“We do anticipate impacting local traffic on this project,” Dreher said. “There’s just no other way we can find to avoid this delay. It’s the Floriston residents that will be most significantly impacted.”
Caltrans will be contacting Floriston residents who use the off-ramps by mid-May, Dreher said, to inform them of the project specifics.
The addition of a retaining wall, a 10-inch concrete overlay, the installation of fiber-optic conduit, ramp rehabilitation and bridge rehabilitation are the primary elements of this project.
