 As an extension of the Good Roads Movement, which had been prominent in Denton County since the early 1910s, residents formed the Good Roads Committee of Lewisville to lobby state and federal officials for funding to create better streets.Lewisville celebrated the paving of the U.S. Route 77 between Denton and Dallas in 1931 with a "Coming Out of the Mud" ceremony.The new pavement closed the "Lewisville Gap" between the two cities, a stretch of dirt road through the city that often became too muddy for travel.
