Project Facts
Key Number: 7148 (Cloverdale Rd. to HP Main Entrance)
Project Number: NH-3230(103)

Chinden Boulevard receives more than 23,000 vehicle trips per day and the number is expected to increase to 31,900 per day by the year 2020. The Idaho Transportation Department will widen Chinden Boulevard between Cloverdale Road and Joplin Road/Mountain View Drive. When complete, Chinden Boulevard will be five lanes from Eagle Road through Garden City.

Project Background
In November 2003, phase one of the Chinden Widening project, between Eagle Road and Cloverdale Road, was completed. The project included:
  • Bicycle lanes, curb, gutter and sidewalk
  • A sound wall on the south side of Chinden Boulevard near the Hobble Creek Subdivision
  • A new traffic signal at Discovery Way
  • Right turn lanes at Park Meadow Way, Discovery Way and Explorer Drive
The project was separated into three phases for several reasons— public convenience, cost, environmental effects and right-of-way acquisition. Phase two, between Hewlett-Packard's main entrance and Joplin Road/Mountain View Drive, was completed in December 2006. Phase three, between Cloverdale Road and Hewlett-Packard's main entrance, is scheduled to begin in April 2007. It is scheduled to be finished in winter of 2007.

Project Description
Like phase one and two, phase three includes widening the road to five lanes, adding bicycle lanes to both sides of the roadway and curb, gutter and sidewalk will be installed. Sidewalk will be installed on the south side of Chinden from Cloverdale Road to Hewlett-Packard. At the project's completion, there will be a sidewalk between Joplin Road and Eagle Road on the south side of Chinden. It will also include mechanically stabilized earth walls and a frontage road on the north side of Chinden between Cloverdale Road and the Hewlett Packard main entrance.

Joplin Road is closed from its western intersection with Chinden (just north of Cloverdale Road) to Ancell Lane. Motorists can access Joplin at its eastern intersection with Chinden (north of the entrance to Mountain View Drive). Following completion of drainage work and pipe installation, the city of Boise will then install underground sewer lines in the same area.

After that is complete, the Ada County Highway District plans to resurface Joplin Road. The closure is expected to last into October of this year. For impacts to traffic during construction, please visit 511.idaho.gov or call 511.
