The closure of North End Road to fix a broken sewer pipe is expected to last up to three weeks.
North End Road was closed in both directions outside West Kensington station on Wednesday (November 15) for Thames Water to carry out emergency works.
Diversions are in place and TfL has warned motorists to expect delays and congestion in the area for up to three weeks.
Speaking to getwestondon a disgruntled Barons Court Road resident, who wished to remain anonymous, said: "There is absolutely no traffic control in the area.
"Residents cannot get out and the emergency services are also caught."
Thames Water estimates the repair will take 18 days to complete due to the depth of the pipe.
A Thames Water spokesman said: "We’re very sorry for the traffic disruption caused by emergency repairs to our broken sewer pipe under North End Road.
"It is essential work to prevent sewage flooding customers’ homes. The repair is complicated as the pipe is seven metres down and is close to the underground station, so we need to dig by hand.
"We’re working hard to complete the work as quickly and as safely as we can."
