New tunnel link proposed for Colombia

Even as work continues on La Linea tunnel in Colombia, the country’s government has received a proposal for an additional tunnel link. A consortium made up of Colombian companies and Italian firms has suggested building a new tunnel to link Quindio and Tolima. Odinsa, Mincivil, Impregilo and Salini are involved in the consortium and have suggested a PPP as being a possible model under which to construct the link, which could cost in the order of US$531 million and would be 8.5km long.

Even as work continues on La Linea tunnel in Colombia, the country’s government has received a proposal for an additional tunnel link. A consortium made up of Colombian companies and Italian firms has suggested building a new tunnel to link Quindio and Tolima. 3214 Odinsa, Mincivil, 3149 Impregilo and Salini are involved in the consortium and have suggested a PPP as being a possible model under which to construct the link, which could cost in the order of US$531 million and would be 8.5km long. The economic case for this new route has yet to be made clear as the tunnel would lie comparatively close to the La Linea tunnel.

Progress with the current La Linea tunnel project in Colombia has been slow due to a series of delays. This link will connect Calarca and Cajamarca in the central Corderilla of the Colombian Andes and at around 8.6km, will be the longest road tunnel in Latin America when complete. When open to traffic La Linea tunnel will reduce travel times along Route 40 between Bogota and Cali and also the port of Buenaventura. This difficult project has met with numerous challenges, from technical, financial and legal standpoints. Altitude has not made the project any easier either and one tunnel portal is at 2,400m above sea level while the other is at 2,500m. However when it is complete the benefit to the Colombian economy will be significant as it will improve transport and cut accidents by replacing a treacherous existing route. From an engineering standpoint, the opening of La Linea tunnel will be a significant achievement for Colombia’s construction industry.

    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

    Further delays to the planned Fehmarn Belt Fixed Link between Germany and Denmark appear likely because of objections to the project during the planning stages, Danish media reported. Government authorities in the German state of Schleswig-Holstein indicated that permission for the project, which focusses on a 17km immersed road and rail tunnel, will probably be given in 2017, and not next year as previously believed. German authorities have received about 3,100 objections to the project that has rise
