This scenic drive on Highway 70 features miles of roadway that criss-cross the north fork of the Feather River and several tributary streams. The highway was started in 1928, and much of it is carved out of solid granite cliffs.

The steel arch bridge, about 30 miles north of Oroville at the Pulga turnoff, is one of the wonders of construction on this breathtaking drive. After three and a half years of labor, construction was completed in 1932 on the 680-foot long structure that is 200 feet above the river and 170 feet above the Western Pacific Railroad bridge! Workers dangled from ropes hung on sheer cliffs to build the abutments to join the canyon's two sides.

The bridge is unique because it not only curves as it crosses the river, but is also banked, creating a span that both curves and twists at a five-degree angle. The best place to view the twist is to turn onto Pulga Road.

You will see several PG&E hydroelectric facilities on the drive and will travel through three tunnels cut out of solid granite near Grizzly River, where it joins the Feather River. One is 1,187 feet long and has viewing windows to look down the steep canyon at the river below.

Chinese laborers built the Western Pacific Railroad line.
