The Western Railway on Sunday completed the dismantling of the 98-year-old road over bridge at Lower Parel station after an 11-hour mega block which saw suspension of train services on the fast line between Churchgate and Dadar and between Churchgate and Bandra on the slow corridor.

The Delisle Bridge was declared unsafe and closed for vehicular traffic following a structural and engineering audit in July last year. The mega block started at 10 pm on Saturday and was scheduled till 9 am on Sunday, an official said.
