ACHD and City of Boise Officials Gather to Celebrate New Whitewater Park Boulevard; Road Opened to Traffic

Boise – This morning, Ada County Highway District (ACHD) and Boise City officials gathered to celebrate the new north-south roadway connection in Boise’s West End between Fairview Avenue and State Street. Construction on the $4.5 million project began in January.  

The new five-lane roadway, called Whitewater Park Boulevard aligns with 30th and 31st streets, and Rose Street, and runs parallel to the Boise River. The road has two travel lanes in each direction and a center turn lane.  

"A remarkable partnership between the City of Boise, area residents and the highway district brought us to this moment. Since the late 1960s, a new north-south connection has been desired to get people into and out of downtown. But Whitewater Park Boulevard will do much more than simply move traffic – although it will do so safely and well," said ACHD Commission President Sara Baker.

Project features include bike lanes, sidewalks, center medians north of Pleasanton Avenue, and three pedestrian crossing signals. A two-lane roundabout was constructed at Stewart Avenue, the entrance to the future Esther Simplot Park. The project also included upgrades to city sewer services.

Some additional finishing work, including city landscaping, will occur in the weeks ahead. Short-term lane restrictions are possible.

Whitewater Park Boulevard was designed by Civil Survey and constructed by Alta Construction, both Idaho-based companies.

Project Background

Numerous planning studies, dating back as far as 1968, have identified the need for a north-south connection to provide better access to downtown Boise. Since early 2000, ACHD and Boise City, with significant public involvement, have focused efforts on designing a roadway that is compatible with the city’s long-term vision for the West End.
