Roadworks near the train station are likely to cause delays this week.
Traffic light refurbishment works are taking place in Allum Lane near the mini roundabout in Borehamwood.
There are two way traffic lights which will be in place from 9.20am-4pm every day until Friday.
There are also three way traffic lights in Radlett at the junction of Theobald Street and Craigwell Avenue.
Hertfordshire County Council suggests these lights will be in place until May 29.
