The road closure and work to repair a pipe under the A23 could last for ‘a number of weeks’, says Thames Water.
The leaking sewer pipe under the road between the Fleming Way and Lowfield Heath roundabouts was detected on Sunday (April 6) after a six-inch diameter hole appeared in the northbound carriageway.
The stretch was immediately closed and has been deemed unsafe for traffic.
From tonight (April 9) one lane of the southbound carriageway between the same two roundabouts will also be closed to allow the repair work to continue.
Mark Taylor, Thames Water head of programme delivery, said: “This is a complex repair and we need to make sure we do it in a way that doesn’t affect the removal of waste from our customers’ properties so it’s taken a lot of planning.
“We’re really sorry for the disruption this is causing but we’re doing all we can to get this fixed as quickly as possible including working through the night.”
A Thames Water spokesperson added:”The leaking pipe carries wastewater away from around a third of properties in Crawley so engineers have had to carefully plan how to divert the flow of water away from the damaged pipe to prevent sewage backing up in other parts of the network.
“This will be done using 1.7km of over ground pipes which will be laid between the area of the burst and another nearby sewer. Thames Water have consulted with local landowners on the placement of the temporary pipes.”
