Bridge to nowhere?

Although many people refer to this as the Elphinstone Bridge, there is no reason to believe this is indeed the one built in 1840 and named after Lord John Elphinstone, the then Governor of Madras. By all accounts, Elphinstone Bridge was broad enough to carry vehicular traffic and, despite one of its pillars being washed away by a flood in the Adayar river. Despite that handicap, Elphinstone Bridge continued to be the link between the San Thome and the Adyar sides of the river, until it was replaced by the Thiru Vi Ka Bridge in 1973. Given such references, we are now faced with a problem of what to call this pathway, which seems to have provided a bridge for pedestrians - most likely fisherfolk - coming from Foreshore Estate to Besant Nagar.

Solving that issue very simply, most people refer to this as the 'Besant Nagar Broken Bridge'. Broken it is, as you can see about 2/3rds of the way through this short video clip. Whole portions of it have fallen away, and there is no bridge on the Foreshore Estate side now. From Besant Nagar, this path juts out almost to the middle of the river, after which there is only a standalone piece a couple of spans long.

Given that there cannot be any hope of traffic on this stretch, it challenges the imagination to come up with a good reason why the Public Works Department (PWD) has recently seen it fit to paint the sides with the black-and-white pattern of a regular pavement; stranger still is their meticulous tarring and marking of a median on this 'road'!
