What really happened?
At the time, PWD officials said that unexpected overloading had damaged its bearings due to an adverse curvature, and then appointed an eight-member committee to look into the damage. A PWD engineer said the damage was not due to breaking of steel rods or concrete spans, but due to the opening of one of the steel locks that binds the 'V' structure of the steel frame laid between the concrete bridge and the pillars of the flyover. However, authorities have insisted they found no deficiency in the design and construction of the flyover, so no action would be taken against the builder.

Citizen speak

Abhishek Vyas, Powai resident
I have been facing problems, as I use this road while coming from Dadar to Powai. Due to this, I end up wasting more than 40 minutes and a lot of fuel. Why can't we have quality work when it comes to public infrastructure? Our bridges are not at par with international standards; abroad, bridges have a lifespan of over 100 years.

Repair plan
The technical team suggested that structural changes needed to be made and a 60-m span of the flyover had to be replaced. While the initial plan was to do a temporary repair, after the committee report, a tender was awarded to Nagarjuna Construction Company. Now, the 60-m span on both the carriageways is being replaced with iron beams and a new concrete viaduct and should be completed by April 2018. After that, authorities say, the bridge will be functional for another 30 years minimum.

Here's the alternative
In the meantime, to avoid the ongoing traffic snarls at the flyover, you can use the Wadala freeway towards Chheda Nagar, Kurla Dairy-Santacruz-Chembur Link Road towards Chheda Nagar, Suman Nagar junction to Chembur junction via Mankhurd towards Chheda Nagar, Chembur junction via Govandi towards Chheda Nagar. Motorists can also use the Sion-Dharavi route to LBS Marg in Ghatkopar and head on the Andheri Link Road.

Are experts aligned?

The flyover was constructed based on traffic estimate of that time; there has been a huge increase in traffic (12 tons to 30 tons). Due to this continuous movement, the steel joints of the bridge had got damaged. We inspected the flyover and suggested the best measure was to completely repair both the arms.

A Senior PWD official
The pier and foundation of the flyover will remain as it is, but the super structure (girders) reconstruction tender has already been awarded and work on Thane-bound carriageway has begun. The work of removing the old distress structure is also in progress, and later, the southbound carriageway will be repaired. While the north-bound carriageway is expected to be ready by December 2017, the south-bound would be repaired by April 2018.
