U.S. Route 830 (US 830) was a U.S. Highway in Washington, which ran between a junction with US 97 near the city of Maryhill and a junction with US 101 near Naselle. The route still (mostly) exists; however it is currently signed as State Route 14 (SR 14) between Maryhill and Vancouver, Interstate 5 (I-5) between Vancouver and Longview, SR 432 for a short stretch through Longview; and SR 4 from Longview to the western terminus near Naselle. The number suggests that US 830 was an auxiliary route of US 30. While US 30 and US 830 never connected, they ran parallel to each other for the entire length of US 830. This route ran on the northern bank of the Columbia River (through Washington) whereas US 30 runs on the river's southern bank, through Oregon.
