Prime Minister of Norway: The Prime Minister of Norway (Norwegian: "statsminister" , literally the "minister of the state") is the political leader of Norway and the Head of the Government of Norway.  The Prime Minister and Cabinet (consisting of all the most senior government department heads) are collectively accountable for their policies and actions to the Monarch, to the Storting (Parliament of Norway), to their political party, and ultimately the electorate.  In practice, since it is nearly impossible for a government to stay in office against the will of the Storting, the Prime Minister is primarily answerable to the Storting.

Strait of Messina Bridge: The Strait of Messina Bridge is a long-planned suspension bridge across the Strait of Messina, a narrow section of water between the eastern tip of Sicily and the southern tip of mainland Italy, specifically between north Messina's Torre Faro and Villa San Giovanni.  In 2006, under Prime Minister Romano Prodi, the project was cancelled.  However, on 6 March 2009, as part of a massive new public works programme, Prime Minister Silvio Berlusconi's government announced that construction of the Messina Bridge would indeed go ahead, pledging €1.3 billion as a contribution to the bridge's total cost, estimated at €6.1 billion.  The bridge would have been the longest suspension bridge in the world, almost doubling the main span of the Akashi-Kaikyo in Japan.  The bridge would have been part of the Line 1 of Trans-European Transport Networks (TEN-T).  Citing budget constraints, the project was cancelled again on 26 February 2013, by Prime Minister Mario Monti's government.

Malaysia–Singapore Second Link: The Malaysia–Singapore Second Link (Malay: Laluan Kedua Malaysia–Singapura ) is a bridge connecting Singapore and Johor, Malaysia.

Inveramsay Bridge: The Inveramsay Bridge is a new bridge carrying the A96 over the Aberdeen to Inverness Line.  The bridge was constructed by Balfour Beatty.  It was inaugurated in March 2016.  The existing bridge has a 4.4 metre height restriction and cannot fit two tall vehicles under it because of the arch which goes under 3.7 metres high in places so traffic lights were put in place so only one row of vehicles could go under the bridge at once, the traffic lights caused bad congestion at rush hour.  For decades this bottleneck was a major problem in the North East's infrastructure with delays being caused on both the A96 and the Aberdeen to Inverness Line, caused by the speed limits imposed on the line following any HGV colliding the bridge, until the bridge could be inspected by a structural engineer.  Despite this there was no political will from the three main UK parties (Conservative Party, Labour Party and the Liberal Democrats) all of whom had been in power in Westminster and/or Holyrood, it was not until the Scottish National Party (SNP) were in power that local MSP, Alex Salmond then First Minister and Keith Brown then Minister for Transport and Veterans announced on 10 February 2011 that tenders for design works to upgrade the Inveramsay Bridge have been given the go-ahead.  There are 1.5 kilometres of new road leading to the bridge.  SuDS is in place at either end of the new part of the A96 leading to the bridge.  The old bridge is still usable for local access.  There is an underpass on the A96 to the south of the bridge which connects the old A96 to Inveramsay.
