Sir, - Delays and tail-backs are a feature of the M50 toll bridge on a daily basis, not just at rush hours as previously. Surely the National Toll Roads Authority could alleviate this major chaos by following the American example.
Increase the toll charge slightly for vehicles travelling one way across the bridge and charge only for that crossing. The idea is that if one crosses a bridge within a day, week or month, one must travel back over it! - Is mise,
