On Monday, September 19, the Town of Basalt began a project to construct a pedestrian underpass under State Highway 82 (SH 82). The project will provide safety improvements for all modes of transportation by building an underpass for non-motorist traffic at the intersection of SH 82 and Basalt Avenue.

The new underpass is designed to be 140 feet long, up to 9 feet tall, 16 feet wide. It will also be illuminated. The project will require the removal of over 8,000 cubic feet of dirt. The construction of the underground path combined with the installation of new traffic signals and an upgraded storm water drainage system are anticipated to improve the flow of traffic and pedestrian safety along this busy stretch of the highway.
The project is located on SH 82 near MP 23.1 in Basalt, approximately 19 miles outside of Aspen. The new underpass will be built on the Aspen side of the SH 82 intersection with Basalt Avenue. It will connect from the Basalt Store area to the bus station and parking lot.
The Town of Basalt awarded United Companies of Mesa County the $6.2 million bid for this project.

The 13-month project began in mid-September and is scheduled for completion in late October 2017. Here is the schedule of major phases of work planned for this project:

• October 2016–March 2017: North Phase
– Temporary bus stop placements
– Building temporary lanes vehicle traffic
– Removal of asphalt and underpass excavation/digging
– Retaining wall construction along Basalt Avenue
• February 2017–August 2017: South Phase
– Asphalt, excavation and retaining wall work
– Final pavement, signals, striping, drainage, safety work
– Reactivation of bus stations
• September 2017–October 20, 2017: Final Phase

Normal working hours for the project will be Monday through Friday, beginning at 7 am and ending at 7 pm, with seasonal adjustments for daylight hours. No work is planned on holidays or weekends.
Additional impacts to travelers on SH 82 should be minimal. Five lanes of traffic will be maintained throughout the project duration, with temporary asphalt side pavement. Traffic control operations will not interfere with the flow of morning and afternoon peak traffic on SH 82.
Traffic speeds will be reduced to 35 mph in the work zone. Please use caution while traveling through the construction zone and follow flaggers’ directions.
