One of Birmingham’s major commuter routes into the city centre is to get a £2.7 million upgrade.
The A45 Coventry Road will become the city’s fourth red route – with a tough zero-tolerance approach to illegal parking.
Council leaders agreed to press ahead with a package of improvements including road widening and better traffic light systems.
Subways at Manor House Lane and Lyndon Road will be filled in and replaced by pedestrian crossings.
Birmingham’s first red route, along the A34 Stratford Road, resulted in an angry backlash from shopkeepers who complained that a crackdown on on-street parking was turning customers away and hitting trade.
But cabinet members are confident that improved public consultation since then will iron out any problems when the changes to the A45 take place.
More than 70 residents and businesses along the Coventry Road support the red route proposals, according to a council report.
However, eight businesses were worried that a one-hour waiting period for street parking spaces will not be long enough.
There are also concerns that deliveries of goods to stores will be made more difficult by the new parking restrictions.
David Bull, the council’s assistant director for development strategy, said the red route would reduce significant delays and congestion along the A45.
