State Route 10 Alternate

Coinciding with the opening of the Smyrna-Dover Bypass portion of the SR 1 toll road, SR 10 Alternate was created in 1993. Expansion of SR 10 (Lebanon Road) was also underway around the same time between U.S. 13 (Dupont Highway) and Bay Road (former U.S. 113) at the toll road. SR 10 Alternate was established along rural Henry Cowgill Road west from Main Street through Woodside. Northeast from the small town, Walnut Shade Road leads SR 10 Alt to Rising Sun and Sorghum Mill Road. The state route continues northward along S State Street (former U.S. 113 Alt) to conclude at SR 10, midway between Camden and Dover AFB.
