Highway Review:
U.S. 377 spends 140 miles in Oklahoma. Of those miles, all of them are duplexed with OK 99.

U.S. 377 comes into the state near the community of Willis. Nine miles later, U.S. 377 and OK 99 intersect OK 32. The highway then goes through two county seats in a 13-mile span, Madill (Marshall County) and Tishomingo (Johnston County). After leaving Tishomingo, the two highways go through three communities (Connerville, Ponotoc, and Fittstown), but do not go through another town until Ada, a distance of almost 40 miles. U.S. 377 and OK 99 go along the eastern side of Ada. OK 3E then becomes multiplexed with the highways for 30 miles from Ada to Seminole. After heading through the heart of Seminole, U.S. 377 and OK 99 continue to Prague and Stroud. U.S. 377 ends at Interstate 44 in Stroud, but all signage for U.S. 377 stops at the OK 66 intersection 1/2 mile south of the interstate.
