Route description

SH-40 at its western terminus, an interchange with I-15

SH-40 begins at a diamond interchange with I-15, located between Malad City and Pocatello, in rural Bannock County. The highway, known locally as Woodland Road, travels due east towards Downey and passes an Idaho Transportation Department maintenance yard before it enters the city of Downey. SH-40 ends at an intersection with US-91 within the city limits of Downey.[1][2][3]

Every year, the Idaho Transportation Department (ITD) conducts a series of surveys on its highways in the state to measure traffic volume. This is expressed in terms of average annual daily traffic (AADT), which is a measure of traffic volume for any average day of the year. In 2011, ITD calculated that 752 vehicles used the highway between I-15 and US-91.[4]
