SIR, - The recent collision at the Peahen junction in St Albans involving an articulated lorry (Herts Advertiser, May 22) raises serious questions.

1.) Why are heavy good vehicles being routed through the city centre?

2.) How dangerous have the Peahen and other central area junctions become for cyclists and pedestrians in particular?

3.) What measures are being taken to reduce air pollution at the Peahen junction - once claimed to be the world's busiest? High levels of benzine and nitrogen dioxide have been recorded there and the monitored air quality consistently fails to meet statutory requirements.

4.) For how much longer is the city centre destined to be so dominated by motor traffic?

5.) Would safety, congestion and air quality at "Peasoup junction" improve and London Road provide a safer, quicker route for park-and-ride buses and cycle traffic if the major development proposed by Tesco gets the go-ahead?
