Various attempts at one-way systems in Grantham have been introduced, but traffic delays are still commonplace. Low railway bridges also add to traffic difficulties with lorries becoming stuck under them. Many promises have been made by the local council for a Grantham bypass road. The latest, the Grantham Southern Relief Road, has been in planning since 2007. Phase one of the project was completed in 2016. Phase Two started in October 2019 which involves building a new junction on the A1 and is due to be complete by Autumn 2021. Phase three which is the main stretch of road is due to start in 2021 and complete by 2023
