“Urgent” investment in the A34 was yesterday called for in Parliament by an Oxford MP.

Oxford West and Abingdon MP Nicola Blackwood put the question of improvements to the road through the county to Chief Secretary to the Treasury Danny Alexander, pictured, in the House of Commons.

But the MP was unhappy with the response.

In the Commons yesterday, she asked: “Does he agree with me that investing in strategic roads like the A34 in my constituency can be key to unlocking vital growth and inward investment in priority sectors and will he investigate the economic case for urgent investment in the A34?”

Mr Alexander said he agreed and said the Government had invested in a project to improve links with the A34 near Newbury and the M4 and work will start in March.

He replied to Miss Blackwood: “I am sure she will agree it will make a considerable difference to the economy in her part of the country.”

Afterwards, she said: “While the Government has committed to some improvements, I do not believe these are sufficient to address the long-term capacity problems. A34 congestion is creating economic barriers as well as daily misery for commuters.”
