Frustration boiled over near the newly inaugurated Sion rail overbridge on Thursday afternoon when around 100 two-wheeler riders, angered by the delay in opening the structure to the public, moved heavy concrete barricades to make way for bikes travelling from Sion station towards Dharavi.

A civic official present near the Sion bridge informed senior mid-day photographer Sayyed Sameer Abedi that the formal inauguration had taken place between 1 pm and 1.30 pm, but the bridge would be fully opened to the public only between 5 pm and 6 pm, as a pandal on one side of the structure was to be dismantled by evening.
