Outbreaks of road rage at a major Birmingham city centre junction should be a thing of the past after council engineers agreed to change traffic light sequences.

Motorists were reportedly coming to blows at the £1.2 million St Chad's Circus island, which last year replaced a huge roundabout.

Problems were caused by filter lights for left-turning lanes from St Chad's Queensway into Snow Hill Queensway and from Great Charles Street into Old Snow Hill. Vehicles going straight on were allowed to share the same lane. Motorists wishing to turn left were becoming increasingly frustrated when their passage was blocked by other cars intending to go straight on.

The left-turn filter lights have now been switched off.

Meanwhile, motorists using the southbound M42 near Coleshill could face delays for the next six months over work on an additional lane. It is being added to the existing two lane stretch of the motorway where the southbound carriageway meets the M6 Toll at Junction 7a.

Speed limits of 50mph will be in place and some overnight closures of the carriageway will be needed while sign gantries are replaced.

The works will add a third lane to the existing southbound M42 from the point where it diverges from the M6 Toll to where the M6 link road merges from Junction 4.

The work is being funded by M6 Toll owners Midland Expressway as part of an agreement it reached with the Government when refinancing the toll road.
