Conversion of 5th Street and 6th Street to Two-Way Traffic Approved

On a split vote, the ACHD Commission approved the conversion of 5th and 6th streets in downtown Boise from one- to two-way operation. The changeover is scheduled to occur in 2019, based on the current capital project plans. Responding to a request from Boise City, the Commission reconsidered the conversion after first rejecting the proposal in June.

The selected option would convert the streets to two-way operation up to Washington Street, where 5th would remain a one-way street to Fort Street. The option avoids negative impacts to the complicated 5th Street, Fort Street and Hays Street intersection, which will be the subject of further study.

Following this option would require new turn lanes at major cross streets to avoid traffic backups -- a key finding of a feasibility study that evaluated the possible conversion. Adding the turn lanes could cost some 48, on-street parking spaces.

Commissioners Paul Woods, Jim Hansen and Kent Goldthorpe voted for the conversion, which was opposed by Commissioners Rebecca Arnold and Sara Baker.

Commissioners initially rejected the conversion in June, but Boise officials argued that Commissioners had not received enough information about the potential, positive economic impacts of a conversion at the earlier meeting and asked for an opportunity to present more material.

At the June 28, 2017 meeting, the Commission left open the possibility of revisiting the conversion in the future but the majority found no compelling reason to make the change, which was opposed by the State of Idaho and the bulk of public input.

Boise City, some downtown developers and the Boise Metro Chamber of Commerce, among others, supported the change, saying two-way streets are safer, promote economic growth and make it easier to navigate. Opponents said the streets function well today and any change risked creating traffic congestion, especially at rush hour, and could make the corridors less friendly for bicyclists.
