In the mid twentieth century, the economy of Crowle declined somewhat, as there was a decline in agriculture, and the transport links which had once contributed to its success took trade away from it. Despite this, there was an expansion in the number of houses, with residential developments on Mill Hill, Wharf Road, Field Side and Godnow Road, and the construction of the M180 motorway, which skirts the southern edge of the town, provided quick access to major centres of employment and shopping.
