The Confluences bridge of the trolley line ready for inauguration

The Confluences bridge will be inaugurated on october 15th. It will allow, from july 2011, the new trolley to cross the Maine between the hospital and the Gaumont multiplexe. The bridge is 293 m long, 17 wide and has a main span 161 m long. It wille be extended from the Maine by a slipway of 90 m long near the cinemas.

Eighteen companies have work on the project. The bridge is constituted by ten sections whose weight is from 30 to 50 tons each. A special crane was set up on the east bank of the Maine. He will overhand the national road 23 from 5 m high. His name was choosen after a public inquiry among 1 500 inhabitants.


The construction of the bridge started in 2008 and was due to be delivered on 2010.The Confluences bridge is part of the first trolley line whose length will be 12 km from Avrillé to La Roseraie linked by twenty five stations. The bridge will cost 27 millions € (7 millions more than expected due to the rise of the steel costs and the necessity to strenghen the foundations till 12 m under the river level), about 10% of the overall cost of the line.
