A main road in Merton will be one-way for up to three months as a gas network is upgraded.

The A217 Bishopsford Road between Mitcham and Rose Hill will be one-way, heading south-bound only.

A signed diversion will be in place for northbound traffic via St Helier Avenue and Morden Road.

SGN has invested £516,000 to replace old gas mains and services with new plastic pipe to ensure a continued safe and reliable gas supply to the area.

In consultation with Merton Council, the work started on Monday (February 12) and will last for approximately three months.

The work will be expected to take place between Monday to Friday, 8am and 6pm and on Saturdays between 8am and 1pm.
