Motorists have been warned to expect further disruption on the Penryn Bypass as work coincides with Falmouth Week.

South West Water said it will be introducing temporary lane restrictions to a section of the A39 tonight, which are likely to be in place throughout the evening.

These will be in addition to the 40mph speed limit in place on the entire stretch of road between Antron Hill at Mabe and Union Road off the Hillhead Roundabout, as the company installs new granular activated carbon filters at the water treatment plant supplying Falmouth and the surrounding area.

A spokesperson said: “As part of our ongoing £10.5million investment to upgrade College Water Treatment Works, we will be installing temporary lane restrictions to a section of the Penryn Bypass carriageway outside the works this evening (Tuesday, August 13) to install a foundation to a new sign.

“The lane restrictions will be in place from 7pm and traffic management will be put in place to minimise any disruption to road users."

He added that the aim was to complete the work and remove the traffic restrictions by 11pm.

“We have been in contact with the organisers of Falmouth Week to plan the work at a time that will cause the least disruption," he said.

This evening's shoreside entertainment comes from The Mariachis, the four-piece South American group famous for the adverts for Doritos and supporting Rod Stewart on his UK stadium tour, who will be performing pop classics with a Mexican twist in Events Square from 7pm.
