History
The road was built in the 1920s to connect the Boise River and the Payette River. State Route 16 originally continued as far as Horseshoe Bend, but that section from Emmett became part of State Route 52 in 1938 .
The main upgrade was an expansion at Star, which became part of the booming Boise region. The bridge over the Boise River was replaced by a wider 4-lane bridge between 2012 and 2014. This is a 3.3 kilometer stretch of 2×2 divided highway opened on August 15, 2014.
Construction of a new highway stretch from Chinden Boulevard to I-84 was completed between 2022 and 2024. Initially, the road was built on one level with traffic lights, but the intersections will eventually have to be replaced by grade-separated connections. Construction of the new road began in August 2022 and will be completed by mid-2024.
Traffic intensities
Every day 14,000 vehicles drive between US 20 and Star and 10,000 vehicles between Star and Emmett.
