The mill district, like the railroad, declined into the 1950s and 1960s. The town suffered two major fires; the second, in 1964, destroyed a large portion of the old mill district. Reconstruction resulted in a controversial urban renewal project featuring a closed-off district, called The Mall, built to replace the destroyed Hanover Street area. Partly in defiance of economic decline, and partly to counter a movement by West Lebanon to declare itself an independent town, Lebanon re-incorporated as a city in 1958.
