On June 20, 2019, NDOT celebrated the completion of the diverging diamond interchange at the SR 157 junction with US 95, which later opened on June 24, 2019. The interchange was a component of a $78 million project which improved a stretch of US 95 in northwest Las Vegas between Ann Road and SR 157, and replaced what was previously an at-grade intersection.
