Post Opening Project Evaluation M40 Junction 15 (Longbridge) Bypass Five Years After Opening Study

This document describes a comprehensive evaluation of the M40 Junction 15 (Longbridge) Bypass, conducted five years after its opening. The bypass was designed to reduce congestion and improve safety, and the evaluation assessed its performance using traffic impact analysis, safety statistics, economic impacts, and environmental considerations. The findings revealed that the bypass successfully reduced journey times, especially during peak hours, and improved traffic diversion and safety, although the latter was not statistically significant. Economic analysis showed lower than expected monetary benefits, but the Benefit-Cost Ratio indicated good value for money. Environmental impacts were generally positive, with some areas of concern noted by local councils. Overall, the bypass met its objectives, continues to provide value, and is expected to contribute to economic growth in the long term. Detailed analyses and recommendations from the evaluation are available for Highways England's use. **This summary was written by an AI model and therefore should not be considered a definitive summary of the report.
