In 2007, the courts ordered a daytime ban on cycle rickshaws along the street, and they were replaced by a fleet of green minibuses, but the ban has been challenged and may not last.

Along it, look out for numbered “heritage buildings” signposted at intervals, with placards outside explaining their historical importance, especially during the 1857 uprising.
