Mortlake Road works bring three weeks of signals

Mortlake Road works between number 67 Lower Richmond Road and the Sheen Lane junction will require temporary multi-way traffic signals for three weeks from 10 August while Cadent Gas completes utility works. The last time this stretch of road saw significant works, delays rippled through Mortlake and East Sheen, so if your usual route takes you along Lower Richmond Road, now is the time to map your alternatives.

Cadent Gas will be installing temporary multi-way signals from outside number 67 Lower Richmond Road to the Sheen Lane junction, with works scheduled to complete by 4 September.

What's happening on Lower Richmond Road

Three weeks of utility works

Cadent Gas will occupy the section of Lower Richmond Road between number 67 and the Sheen Lane junction in Mortlake from 10 August through 4 September. The works require temporary multi-way traffic signals, which means drivers should expect delays during peak hours and allow extra time for journeys through this part of the borough. The section affected sits on a key route between Mortlake and East Sheen, and previous works on this road have caused ripple delays into Clifford Avenue and surrounding streets.

Your best approach is to avoid the area entirely if your journey allows it.

Alternative routes and practical options

Plan around the signals

If you regularly drive through Mortlake along Lower Richmond Road, consider using Upper Richmond Road West or routing via Sheen Lane and Mortlake High Street instead, depending on your destination. Cyclists may find the towpath a more predictable option during the works period, particularly during morning and evening peaks. Bus services that use this section, including routes serving East Sheen and Barnes, may experience delays, so check live departure boards if you rely on public transport through this area.

The three-week timeframe means the works will still be in place as the new school term begins in early September, so parents on the school run will want to test alternative routes before then.

What this means for you

If Lower Richmond Road is part of your daily commute or school run, test your alternative route this week rather than on 10 August when the signals go live. Drivers heading between Mortlake and East Sheen can use Upper Richmond Road West, though you may find similar congestion there once other drivers make the same switch. If you cycle, the Thames towpath offers a reliable alternative that avoids road traffic entirely. For queries about the works themselves or to report any issues during the three-week period, contact Cadent Gas directly on 08000 159 057. Keep an eye on whether Clifford Avenue remains clear during this period, as simultaneous works on both roads would significantly limit options for getting through this part of the borough.

Three weeks of temporary signals on Lower Richmond Road will test your patience if this is your usual route, but planning an alternative now will save you time once works begin on 10 August. The key is avoiding the area entirely rather than sitting in queues that may stretch back towards Barnes or East Sheen.

Previous utility works on this section caused notable congestion that spread into neighbouring streets, and local residents will remember the knock-on effect well.
