The Brynglas Tunnels carry the M4 under Brynglas Hill in Newport, Wales. The 360-metre-long (390 yd) tunnels are the first and only twin–bored tunnels in the UK motorway network.The tunnels and adjacent M4 motorway Usk bridge were originally planned by Newport Corporation in August 1959 in a plan submitted to the Ministry of Transport. Work started on the £3m tunnels project - led by engineer Sir Owen Williams on 10 September 1962. Both structures were complete and open to traffic on 5 May 1967. During the construction several houses on Brynglas Road (where the modern Newport Lodge Hotel now stands) had to be demolished due to structural weaknesses caused by the tunnelling and prompting questions in the House of Commons.
