The British government is considering building a bridge between Scotland and Northern Ireland. British media report that on Monday.

A price tag of at least £ 15 billion is attached to the construction.

According to the British broadcaster BBC, government officials are currently investigating the feasibility of two possible options. A first option provides a bridge between the Scottish Mull of Kintyre and the Northern Irish Torr Head.

The second option is a bridge of some 34 kilometres between Portpatrick (Scotland) and Larne (Northern Ireland). According to various media, the last bridge is preferred.

The bridge should resemble the Öresund bridge, the bridge between Sweden and Denmark.

British Prime Minister Boris Johnson has called the bridge a “very interesting idea”. His spokesman James Slack emphasises that the prime minister is “ambitious” in infrastructure projects. The Irish government leader Leo Varadkar also finds the proposal “worth investigating,” BBC reports.

Critics, however, disagree. For example, Wes Streeting, a Labor MP, is talking about a money-wasting “vanity project” from Boris Johnson.

Many opponents also point to Johnson’s failed plan for a Garden Bridge in London. As the mayor of London, Johnson wanted to work on a pedestrian bridge with trees and plants over the Thames. That bridge never came.
