The Transport Secretary says improving the A303 remains his "biggest priority" for the South West's roads network.
The Government's looking to dual large sections of it, build a tunnel at Stonehenge and improve the connecting A358 between Ilminster and the M5 at Taunton.
Chris Grayling has been speaking after meeting council bosses and business leaders at Somerset County Cricket Club.
Officials also discussed the M5 and work to improve the region's rail lines.
Stephen Henagulph, Chief Executive of Somerset Chamber of Commerce, told the Transport Secretary 'many in the business community feel the region is not taken as seriously as other parts of the UK - with the focus of government seeming to be directed towards the Northern Powerhouse and Midlands Engine'.
Speaking afterwards he said: "This was a welcome opportunity to hear from the Secretary of State for Transport and whilst he confirmed that a number of actions are underway and funding is in place to support them, he was still not sufficiently specific in terms of timing for long-awaited projects such as the dualling of the A303.
"We will continue to work closely with our colleagues at the British Chambers of Commerce to keep the pressure on and ensure that these vital projects do not slip down the government's agenda."
Somerset County Council leader David Fothergill said: "I was very pleased to welcome the Secretary of State to Taunton and was grateful for the opportunity to discuss some of the issues which are so important to Somerset and the wider South West region.
"It was great to hear about the plans to upgrade the A303 and A358 and continued investment in our region."
