Mumbai, Nov 5 (TIWN): Maharashtra has a stupendous 35,000-plus big and small bridges on roads in village, towns, cities, state or national highways, posing mind-boggling challenges for their regular upkeep and maintenance, with multiple agencies involved, but recording barely 100 structures crashing since 2000, top officials said.

As per government data, under the state’s Public Works Department (PWD) jurisdiction, there are 146 small, 105 big and five long bridges (total 256) from the pre-Independence era, some dating back to over 350 years and still functional.

In the post-Independence era, the state recorded massive development since 1957, with around 16,000 small, 2100 big and 100 long (total 18,200) bridges being constructed.

Besides, there are some 12,000, including 2,000 major bridges, on the national highways crisscrossing the state, an estimated 4,000 (total 16,000) in various civic bodies’ jurisdictions, like some 450-odd in Mumbai, not counting another huge number of bridges on the railway networks.

Despite the huge numbers of bridges, in the past 22 years, barely around 100 medium or small have crashed – 75 percent of them comprising masonry design and the rest raft design – in different parts of the state.

The worst crash was the washout of 106-year-old British-era masonry bridge on the heavily-flooded Savitri River near Mahad in Ratnagiri on August 2, 2016, which swept away two ST buses and around 10 other private vehicles with the death toll touching 40.

There have been other smaller crashes in Mumbai and other parts of the state in the past two decades though with lesser casualties or fatalities.

As per Indian Road Congress (IRC) norms, a “small bridge” spans 06-60 metres, a “big bridge” is 60-200 metres and a “long bridge” is 200 metres plus and can go upto a few kms in length, each posing unique challenges for their upkeep and safety.
