State Highway 119 is a 63.7 mi (102.5 km) long state highway in north central Colorado. It extends in a southwest to northeast direction, from a junction with U.S. Highway 6 in Clear Creek Canyon between Golden and Idaho Springs to a junction with I-25 east of Longmont. The southwest portion of the road is a scenic mountain drive providing dramatic vistas of the Front Range, while the northeast portion is a busy interurban thoroughfare. The city of Boulder separates these two vastly different sections of SH 119.
