Jefferson Street, 16th Street to 1st Street (Downtown Boise Implementation Plan)

General Description

Project update as of 7/13/16:

Commissioners reviewed the plan for Jefferson Street, directing staff on the kind of bicycle facilities to add to the street in the fall of 2016 when the conversion from one- to two-way operation is completed.

Concerned about the potential loss of more than 100 parking spaces, the Commission majority told ACHD staff to put in sharrows -- shared lane markings indicating where bicyclists would ride within the regular traffic vehicle lane -- on Jefferson from 1st to 16th streets. The sharrows will be applied by early October, when the paving of the Jefferson is expected to be finished and striping of the road completed.

The adopted Downtown Boise Implementation Plan from late 2013 called for Jefferson to receive bike lanes, which would come at the cost of the parking. The City of Boise strongly supported altering the plan to utilize sharrows.


Project update as of 5/9/16:  The Preconstruction Meeting will be held on May 13. The Notice to Proceed is May 18.

Beginning as early as May 18, 2016 construction will begin on the Downtown Boise Implementation Plan (DBIP) project on Jefferson Street between 16th and 1st streets. Construction is scheduled for completion in November.
