As the car took over American life after World War II, the downtown, which already was facing problems due to a drop in expendable income, was largely vacated as business moved to suburban shopping malls. The theatres and department stores left, and much smaller enterprises moved in if anything. Many buildings were torn down for parking lots, and many others burned down, and were not replaced. Others had their top floors removed to reduce tax bills and many facades were "modernized" destroying the Victorian character of the downtown. Road widening and other improvements destroyed a row of business next to city hall, as well as the area that has become the Lord Overpass. The construction of the Lowell Connector around 1960 was surprisingly unintrusive for an urban interstate, but that was only because plans to extend it to East Merrimack Street by way of Back Central and the Concord Riverfront were cancelled. Talk began on filling in the canals to make more real estate.
