Access to Businesses
The Boulder Farmers' Market will remain in its current location. Market attendees are encouraged to use other transportation options or to approach from Canyon Boulevard and park in the downtown parking garages.

The following businesses along Arapahoe Avenue will remain open throughout construction and appreciate your continued business.

Construction

There will be traffic and other construction impacts throughout the entire 15-to-18-month construction period. There will be three phases of construction, each with distinct traffic impacts. The most impactful work, in terms of traffic, will take place during the summers of 2013 and 2014 to take advantage of the general reduction in travelers during the summer months due to less school and university activity.

• Phase 1: June 3 through mid-August 2013 – Stormwater and other utility relocation work. 
Arapahoe Avenue is reduced to one eastbound lane of traffic between Folsom and 15th streets, with westbound traffic and both directions of the JUMP bus detoured onto Canyon Boulevard. The full-time westbound lane closure will remain in place through mid-August 2013. Travelers are encouraged to bike or walk along the Boulder Creek Path, ride buses, or use Canyon Boulevard and the downtown parking garages if driving.

• Phase 2: Mid-August 2013 through May 2014 – Construction of curbs, gutters, driveways, and sidewalks, and irrigation relocation. 
Traffic will be reduced from three to two lanes during off-peak hours. The JUMP bus will remain on Arapahoe Avenue, but there may be temporary bus stop closures.

• Phase 3: Late May 2014 through mid-August 2014 – Concrete paving. 
There will be a full-time closure in effect with one lane of eastbound traffic open on Arapahoe Avenue between Folsom and 15th Streets.  Westbound vehicular traffic and the JUMP bus will be detoured onto Canyon Boulevard.

In September and October 2014, there will be finish work and landscaping that will have include daytime single-lane closures in both directions on Arapahoe Avenue.
