Kerch Strait Bridge, Russia
The Kerch Strait Bridge is an 19km parallel road-rail bridge that will connect Kerch Peninsula of Crimea, Ukraine, to the Taman Peninsula of Krasnodar Krai, Russia.
Construction of one of the biggest bridges in Russia started in 2015. The highway is expected to be opened in 2018, while the rail line is expected to be completed in 2019. The bridge is expected to be utilised by up to 40,000 vehicles and 47 pairs of trains a day.
The Russian Federation is developing the Kerch Strait Bridge, which is estimated to cost RUR227.92bn (approximately $3.5bn) to construct, according to July 2016 estimates.
Kerch Strait bridge details
The State Corporation 'Bank for Development and Foreign Economic Affairs (Vnesheconombank)', the Russian Transport Ministry, and the Ukrainian Transport and Communications Ministry signed a memorandum of understanding in November 2010 for the construction of a transport crossing over the Kerch Strait.
The agreement between the Russian Federation and Ukraine to construct a co-operative transport crossing project over the Kerch Strait was formalised on 17 December 2013.
The route of the bridge will start on Taman Peninsula and traverse through the existing 5km dam and the island of Tuzla. It will then cross the Kerch Strait and enter the Crimean coast via cape Ak-Burun.
The bridge will create a direct toll-free road link between Crimea and Sevastopol, provide an uninterrupted rail service, and increase tourist attractiveness of the region and investment attractiveness of the Crimea and Kuban.
The project includes the construction of two parallel structures, namely a four-lane road and a double-track rail road. The car route (road) will consist of four strips allowing a speed of up to 120km/h.
Passenger trains are expected to run at a maximum speed of 120km/h, while freight trains will run at 80km/h.
The project will feature a 227m-long steel arch support, which will be 35m-tall and does not pose any obstruction to the ships passing underneath the bridge.
Kerch Bridge construction
The construction of the bridge connecting Crimea will involve the participation of approximately 20 Russian construction companies.
The bridge construction will include the submerging of more than 7,000 piles of three types, and is expected to use more than 12.5Mt of construction materials. It will stand on pillars with foundations for structures at a depth between 50m to 94m, with more than 100 steel tubular piles.
The first beams for the Kerch bridge span structures were shipped from Voronezh, along with the start of construction of the bridge towers in the offshore areas in May 2016. More than five million ton of cargo was delivered to the Kerch Bridge as of June 2016.
Construction of the first marine bridge support was completed in September 2016, during which the construction of main support infrastructures on both sides of the Kerch Strait was also completed.
Piling works on the foundations of 46 road and rail supports for the first section of the bridge between the shoreline and the Tuzla scythe was completed by October 2016.
The first stone-laying ceremony for the road connecting to the bridge across the Kerch Strait was conducted on 22 February 2017.
Construction of the fairway started in May 2017, and more than 5,100 piles, 48,000t of harvested superstructures, and approximately 7,800t of steel shipping arches were shipped as of June 2017.
The 10t fairway support arch is planned to be transported and mounted during August and September 2017 through a naval operation.
Key players involved with the Kerch Strait Bridge
Stroigazmontazh was awarded the contract for designing and building the bridge across the Kerch Strait by the Ministry of Transport of the Russian Federation in February 2015. Stroygazmontazh established SGM-Most for implementing the bridge construction.
In March 2016, SGM-Most awarded a RUR96.9bn construction contract to Mostotrest for installing pillars and spans on the entire length of the road and rail bridges. The contractual scope includes installation of bored piles, raft foundations, tower bodies, assembling and launching of superstructures, fuse superstructures, and the supporting elements.
PKU Uprdor Taman, a Russian federal institution under the Federal Road Agency (Rosavtodor), was entrusted with the Kerch Bridge construction management.
Stroigazmontazh subcontracted the Institute Giprostroymost-Saint-Petersburg for the Kerch Bridge design in April 2015. STG-Eko was engaged by Institute Giprostroymost to conduct engineering and ecological studies as part of the environmental impact assessment.
FAU Glavgosekspertiza Rossii conducted the project documentation works for the Kerch Bridge.
Voronezhstalmost is the supplier of steel structures for the project, while DSK was engaged to improve the access roads to the bridge on both sides of the Kerch Strait.
Karst was contracted for constructing the foundation pilings and supports for the project, while Institut Stroiproekt was engaged for constructing the highway segments of the project.
