The main transport to and from Brigg is by road. The A18 passes east–west through the town, connecting into the national road network, with the A1084 (Bigby Road) heading south–east to Caistor. The M180 bypasses the town carrying longer distance traffic, including the A15 between Lincoln and Hull. A few bus services operate in the town, most of which travel to Scunthorpe and stop in intermediate villages. On Thursdays a bus service travels solely within the town, carrying passengers to and from the weekly market.
