Two councils will unite to tell the Government what they think of the proposed Worthing-Lancing bypass.

Councillors from Adur district and Worthing borough agreed a joint response to the Government's coming decision on multi-million pound road plans would have a greater impact.

The proposed bypass, outlined in the South Coast Multi-Modal Study, could involve two tunnels being built to draw traffic away from the often congested A27 at Worthing. The project would cost £275 million.

Members from both councils asked officers to prepare a response to the plans and repeated calls for more information about where the tunnels would be located.

The multi-modal study, published last September, does not specify where the tunnels would be built, limiting discussion on the matter.

A report said homes along the A27 may have to be compulsorily purchased to make way for the tunnels, heightening concerns.

Referring to where the traffic jams at Worthing tail back to, Adur leader Neil Parkin said: "We do feel a Worthing bypass and getting traffic moving around Worthing is not just a Worthing problem.

"It affects the economic viability of businesses and quality of life of Adur residents who want to go beyond Duncton Lane, Sompting, on a Saturday afternoon or visit loved ones in Worthing Hospital but can't because it's gridlocked."

The Government is expected to announce its decision on the road plans in the spring.
