外文翻译 Quick fix: replacement of an old wooden bridge in St Petersburg was completed earlier this year. Rising traffic levels and development demands led to an old tramway bridge being rebuilt as a cable-stayed crossing in the Russian city of St Petersburg. The new Lazarevsky Bridge across the Malaya Nevka was opened to traffic earlier this year, replacing an old wooden structure which was built for trams but recently had only been used by pedestrians. The bridge is located in Petrograd district and connects Krestovsky and Petrogradsky Islands along Pionerskaya and Sportivnaya Streets, both of which are importanat links for local traffic.

Its total length was 141m and its width was 11m, the deck consisting of metal baulks and wooden plank flooring. The timber post piers rested on piled foundations of steel pipes. But in 2002 the tramway was closed and since then, the bridge has only been used by pedestrians. Its location meant that Lazarevsky Bridge served the western part of the city--the Petrograd districts including Krestovsky island. All the road traffic to Krestovsky island used the main Krestovsky Bridge which as a consequence was considerably overloaded. Since the Lazarevsky Bridge carried no vehicular traffic it was not considered part of the road network of the district. But plans to build a new stadium at the Seaside Victory Park on Krestovsky Island just 3km from the bridge site meant that a reliable transport con
