The first tunnels are being excavated for the huge bypass tunnel in Sweden’s capital Stockholm – Adrian Greeman writes. After years of preparation and design, blasting and rock moving for Sweden's largest infrastructure project began south of the city this year. It sets in train a decade-long project that will create a new half-ring dual three-lane motorway for the city, 20km long. With most of it deep underground, it will also be one of Europe's largest ever road tunnels. The scheme is aimed at transformin

A major new highway project connecting the UK’s university cities of Oxford and Cambridge has been proposed. A new study by the Department for Transport (DfT) has set out the case to improve connections between Oxford, Milton Keynes and Cambridge. The Oxford to Cambridge expressway strategic study is one of a number of studies aimed at addressing some of the biggest challenges facing the road network in the UK.

The tender process for a major new highway project in Argentina is expected to commence in 2017. The new highway will connect Santa Fe with San Justo and will measure 82km in length. The project is expected to cost in the region of US$166 million to construct, with funding being supplied by the Inter-American Development Bank. The schedule for the project has not been finalised and will not be clarified until the tender is awarded but construction work could commence during 2018.

The UK’s Department for Transport (DfT) has put forward five alternate route options for a new highway connecting the cities of Manchester and Sheffield. The project looks likely to include a major tunnel section measuring as much as 20-30km in length that would run under the Peak District. The aim of the project would be to cut journey times between the two cities as the existing transport routes are prone to peak period congestion and delays at present. The route would connect either the M60 or M67 motorw

Namibia is investing in road development with a series of major projects now being targeted. The country has a major need to improve its road system, which does not have sufficient capacity in some urban areas and also suffers from serious safety concerns right across the nation. The country’s road authority will invest close to US$39 million to improve roads in the Oshana, Kavango, Oshikoto and Ohangwena regions.

Construction work on Serbia’s Ljig-Preljina highway, the Corridor 11 Project, is being delayed. The delay has been caused by complications involving the construction of the tunnel and bridge sections. The construction work is being carried out by the Azerbaijan contractor Azvirt, with local firms carrying out sub-contracting projects. The new route is expected to open around 40 days later than originally expected as a result. Meanwhile the improving political relations between Serbia and its neighbour Ko
