Investigations into the Croxley Rail Link will continue into next week as traffic control is put in place in Baldwins Lane to allow county council staff to carry out investigations.
Stop/go boards will be stationed by the railway bridge, near Watford Road, from today until April 10.
Motorists can expect delays between 9.30am and 4.30pm as investigations into the impending rail link continue.
Hertfordshire County Council is responsible for the work.
