Interstate 97
Interstate 97 (I-97) is a part of the Interstate Highway System that runs entirely within Anne Arundel County, Maryland. The intrastate Interstate runs from U.S. Route 50 (US 50) and US 301 in Parole near Annapolis north to I-695 and I-895 in Brooklyn Park near Baltimore. The Interstate is the primary highway between Baltimore and Annapolis. I‑97 connects Annapolis with Baltimore–Washington International Airport and links the northern Anne Arundel County communities of Crownsville, Millersville, Severna Park, Glen Burnie, and Ferndale. It is the shortest primary Interstate Highway.
U.S. Route 97
US 97 goes through the city of Klamath Falls before continuing north to Bend and the junction of US 20. From there, US 97 intersects US 26 at Madras before US 197 continues to the northwest, and US 97 continues northeast to I-84 and the Columbia River. The section from Sunriver to just north of Redmond is a dual carriageway with two lanes in each direction.
North of the Columbia River, US 97 intersects SR 14 before continuing north. Between Goldendale and Yakima the highway passes over Satus Pass. In Yakima, US 97 runs concurrently with I-82 north to Ellensburg and then on I-90 west before continuing north into Wenatchee National Forest to US 2. Both routes continue east into Wenatchee and then north along the eastern bank of the Columbia River, before US 2 continues east and US 97 continues north. US 97 Alternate continues along the western bank of the river, before US 97 shifts to the western side of the river. US 97 intersects SR 20 near Omak before US 97 crosses the Canada–US border north of Oroville, Washington and becomes British Columbia Highway 97 at Osoyoos, BC. BC Highway 97 is the longest uninterrupted highway in the province winding south-to-north, eventually becoming part of the Alaska Highway and passing into the Yukon territory. However, the '97' designation ends at the BC/Yukon border.
