Met Line Update

Utility Work

In order to build the new viaduct over Baldwins Lane and Watford Road, we must divert a number of utilities in the area.  These works began in early March and are due to take six months to complete.

The next phase will take place from Monday 18 April to Sunday 29 May 2016. The works involve excavating areas of the carriageway and footway in order to divert existing gas and electrical services.

The majority of the work will take place between 0800hrs and 1800hrs from Monday to Sunday.

Where traffic management is required for the works, this is expected to take place during the following times:

  • Monday 18 April to Sunday 29 May (all day): The pedestrian crossing across Watford Road will continue to be closed and a temporary crossing put in place.
  • Weekdays (from 9.30am to 4pm) and weekends (all day): Single lane closure on the Watford Road roundabout and approaches to and from Baldwins Lane and Watford Road.
  • Weekdays (from 9.30am to 4pm): Single lane working on Baldwins Lane managed by stop/go signage.

The above outlines the anticipated arrangements we aim to have in place. There is a possibility the electrical cables will be deeper than our surveys have suggested. If this is the case additional traffic management may need to be put in place.  We will communicate this to local residents if this occurs.

The work is still subject to final approvals from Hertfordshire County Council Highways. We will update you on the further phases of work in due course.
