Two new tunnel links for Turkey

Two new tunnel connections in Turkey will improve transport in key areas. The new Kemerhisar-Pozanti Highway features tunnels along its length and this key route will improve connections between the country’s capital Ankara and its commercial centre Istanbul as well as to the south-east of the country.

The new Konak Tunnel in the port city of Izmir will cut journey times

Two new tunnel connections in Turkey will improve transport in key areas. The new Kemerhisar-Pozanti Highway features tunnels along its length and this key route will improve connections between the country’s capital Ankara and its commercial centre Istanbul as well as to the south-east of the country.

The highway will have wider benefits too as it will allow better transportation through Turkey between Europe and the Middle East. And in the busy port city of Izmir, the new Konak Tunnel will reduce journey times considerably.

Once the tunnel link is complete it will cut congestion between between Konak and Yeildere in the city.

In addition, 2643 Egis has signed a contract for the operation and maintenance of the Gebze-zmir highway in Turkey. The agreement was signed with OTOYOL, the concessionaire for the Turkish General Directorate of Highways (3337 KGM). This is the second major contract award for Egis in Turkey, following the Eurasia Tunnel deal, for a 5.4km twin-deck tunnel under the Bosphorus.

OTOYOL was selected by KGM as the private concessionaire for the project, and is itself a firm established for the purpose of the project by five Turkish companies: 3338 Nurol naat ve Ticaret; Özaltin naat Ticaret ve Sanayi; 3340 Makyol naat Sanayi Turizm ve Ticaret; 4149 Yüksel naat; 3342 Göçay naat Taahhüt ve Ticaret; and one Italian company, 1324 Astaldi.

After a competitive bidding process, Egis was selected by OTOYOL as its operation partner.

Gebze-Izmir Project

The Gebze-zmir Project is a tolled highway project procured by KGM under a build, operate and transfer (BOT) model. This is the largest BOT project in Turkey to date. It includes 420km of highway (2x3 lanes) between Gebze (on the North shore of zmit Bay) and zmir, as well as a 3km suspension bridge crossing zmit bay, three tunnels with a total length of 6km and 20 toll stations.

The project will be implemented in two phases. The first phase from Gebze to km 58 will include the 3km Izmit bay suspension bridge which is one of the longest suspension bridges in the world by the length of central span.

There is considerable requirement in Turkey for additional roads and highways as the country’s vehicle population is growing significantly. The number of registered vehicles in the country increased by 2% in April 2013 to reach 17.35 million, and in the period from January-April 2013, 372,000 new vehicles were registered while 55,000 old vehicles were removed from the registry.

Out of the total 17.35 million vehicles, 51% are passenger cars; 16.4% pick-up trucks; 15.5% motorbikes; 8.8% tractors; 4.3% trucks; 2.3% minibuses; 1.4% coaches; and 0.2% special-use vehicles.

    The opening of a new bridge in Kazakhstan that spans the Irtysh River is now offering a shorter route for drivers. The link is 12.3km long and is now the longest such structure in Central Asia, while the project cost around US$157 million. Its length was necessary as the bridge crosses a floodplain area, with a channel that can widen considerably following periods of heavy rain. Located in the country’s Pavlodar region, the bridge cuts the route used previously by over 40km. The bridge is expected to carry

    A feasibility study is underway for the highway project to connect Colombia’s capital Bogota with the country’s second city, Medellin. The 427km route will be of major benefit to the country by cutting journey times between the two cities to around five hours. However the project looks likely to face serious challenges, particularly with regard to the topography of key sections of the route. Tunnels may have to be constructed to avoid some of the steeper climbs on the current route. Widening the existing ro
