branches off from I-695. Bypass A bypass route may traverse around a city, or may run through it with the mainline bypassing. In a typical 3-digit Interstate Highway, bypasses usually have both its two termini junctioned with another Interstate highway. Bypass routes are preceded by an even number in the first digit. Examples include: I-220 in Louisiana serves as a bypass of downtown Shreveport. I-440 forms a loop around the south side of Nashville. I-890 travels through downtown Schenectady, which I-90 avoids. In the case of an auxiliary Interstate highway which has both ends at Interstates but not the same Interstate, some states treat these as bypasses while others treat these as spurs — see Spur route above. Beltway A beltway (also known as a loop route) completely surrounds a metropolitan city, and it is often connected with multiple junctions to other routes. Unlike other auxiliary Interstate Highways (and by extension, all primary Interstate Highways), beltways do not have termini; however, they have a place where the highway mileage resets to zero. Beltways are also preceded by an even number in the first digit. Some examples of beltways include: I-275 in Ohio, Kentucky and Indiana encircles the city of Cincinnati. I-465 in Indiana encircles the city of Indianapolis. I-495 in Maryland and Virginia encircles the city of Washington, D.C. and is referred to as "The Capital Beltway".
