West Midlands Mayor Andy Street has told Birmingham City Council that it is jeopardising the Commonwealth Games by attempting to knock down the Perry Barr Flyover.
The city council made the decision to demolish the flyover four months ago, but work has not begun on the structure.
The A34 Perry Bar Highway links Birmingham City Centre to Walsall. A 15,000-strong petition was put together opposing the plans.
The Mayor has now renewed his calls to keep the flyover in place due to the delays to work and the risk it poses to the Commonwealth Games in 2022.
Birmingham City Council say there has been no delay to the timetable for the A34 highway improvement scheme.
Councillor Waseem Zaffar said: “We have always been very clear that the A34 improvements are not about the Commonwealth Games.
"It is about ensuring the transport infrastructure in Perry Barr can meet the needs of an increased population as we are building 5,000 new homes as part of a wider £0.5 billion regeneration of the area."
