U.S. Route 830


U.S. Route 830,, was a U.S. Highway in Washington, which ran between a junction with U.S. Route 97 near the city of Maryhill and a junction with U.S Route 101 near Ilwaco. The route still exists; however it is currently signed as Washington State Route 14 between Maryhill and Vancouver, Interstate 5 between Vancouver and Longview, Washington State Route 432 for a short stretch through Longview; and Washington State Route 4 from Longview to the western terminus near Ilwaco. The number suggests that US 830 was an auxiliary route of U.S. Route 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 whereas US 30 runs on the river's southern bank, through Oregon.

History

US 830 was created in 1926 as part of the initial set of national numbered highways, running from US 101 at Megler to US 97 near Maryhill. When it existed, US 830 was the highest-numbered route in the U.S. Highway system. The highest numbered route still in existence is US 730.
The stretch of US 830 which is now I‑5 was at one point concurrent with U.S. Route 99. The stretch of US 830 between Maryhill and Dalleport was formerly concurrent with U.S. Route 197 from 1952 onward; now Dallesport is the northern terminus of US 197.
US 830 was decommissioned in 1968 and was replaced by SR 4, I‑5, and SR 14.
