 It was previously accessible by railroad however the railway is no longer in use largely due to the 1964 Good Friday earthquake and the resulting destruction it caused to the Million Dollar Bridge.The longest road is the Copper River Highway which follows the old railbed of the Copper River and Northwestern Railway for 49.5 miles (79.7 km).The first 11 miles (17.7 km) east of Cordova is paved and the rest is gravel.
