National Highways is working towards opening the Trevalso underpass at Zelah in July as part of the A30 dualling scheme from Chiverton to Carland Cross.

Pennycomequick Lane and the Church Lane underpass will open soon after, while Cornish hedging work will also be completed in the summer followed by the planting of 40,000 trees across the scheme landscape in late autumn.

Since opening the new dual carriageway last June, the old A30 has been transformed into the B3285 and B3288 between the Chybucca and Carland junctions. National Highways and principal contractors Costain have been continuing ancillary work through the winter and spring, including local road connections, Cornish hedging and the planting of 44,000 trees.

Following resurfacing and road marking work around the Chiverton gyratory this month and the completion of footpath work at Chybucca, further finishing work will be carried out under four weeks of overnight closures starting imminently.

Final resurfacing work at the Carland junction will take place under a week of overnight closures (8pm to 6am, weeknights) from Monday, June 9, between Mitchell and the Chiverton interchange, along with a closure of the A39 and B3285 roads.

New, permanent signage will be installed, along with the completion of footpaths and road markings.

Phased finishing works, including signage installation and drainage, will also be carried out under three weeks of overnight weeknight closures (8pm to 6am) from Monday, June 16.

Varying and clearly signed diversion routes will be in place to enable the works. The latest information is available on the scheme web page and via X (formerly Twitter) at @HighwaysSWEST.

Andrew Alcorn, National Highways’ Programme Manager for the A30 Chiverton to Carland Cross scheme, said: “Opening the new dual carriageway has made a significant and positive difference to people’s journey times, and opening up the old A30 will improve local connectivity and bring benefits to communities and residents alongside the new road.

“We’ve progressed a significant amount of ancillary work, including planting, hedging and landscaping, and we’re in touching distance of the finishing line now. We thank people in advance for their continued co-operation and patience while we carry out these final works.”

The project team is continuing to work closely with Cornwall Council and other key local stakeholders and is keeping local communities fully informed as the scheme approaches completion.

In the meantime, latest information on the scheme is available at National Highways’ A30 Chiverton to Carland Cross web page at nationalhighways.co.uk.

The cost of developing the scheme has been funded by an £8 million contribution from the European Regional Development Fund, with an additional £12 million for the construction phase. The remainder of the cost of developing and delivering the scheme has been funded by central Government.
