Further to the AWPR, Balfour Beatty was working with Carillion on two other contracts, comprising of operations on the A14 road in Cambridgeshire and a motorway contract in the northwest of England.

The financial impact for Balfour Beatty was estimated to be in the range of £35 million ($48 million) and £45 million, the company said in a statement. Joe Brent, an analyst at Liberum, told CNBC in an email on Monday that he anticipated an adverse cash impact at Balfour Beatty of around £40 million but “no material impact elsewhere.”

In a statement, the international infrastructure group said it would continue to work with its customers and ensure it meets its contractual commitments.
