A bridge in Grantham has the worst record in the country for being hit by lorries - for the second year in a row.
Network Rail is looking at ways of protecting the bridges
Springfield Road bridge on the A607 was struck 24 times last year, according to Network Rail.
Bridges on Harlaxton Road and Barrowby Road, Grantham also feature in the top 10 most bashed in the country.
Network Rail, which is responsible for the bridges, said wherever possible it pursued hauliers to pay for the damage caused by their lorries.
Spokesman Ben Herbert said: "Unfortunately we do have a certain number of hit-and-runs where the drivers don't stop.
"Ultimately what happens is that we will have to pay train operators compensation for delays to their services."
He added the company had tried different solutions to the problems in Grantham.
"Springfield Road and Barrowby Road now have very large crash protection beams which basically sit in front of the bridge structure itself, so when a lorry actually strikes the bridge, it doesn't hit the structure itself but the beam.
"We're looking at increasing use of technology to make sure we can reopen the railway line as quickly as possible."
