Post Opening Project Evaluation A453 Widening M1 Junction 24 to A52 - One Year After

This document describes an evaluation of the A453 Widening scheme, which aimed to reduce congestion and improve transportation by converting a single carriageway into a dual carriageway. The evaluation, conducted one year after the scheme's opening, employed traffic analysis, safety assessments, and environmental impact studies. Results showed increased traffic, better journey times, fewer collisions, and environmental impacts that were in line with predictions. The scheme largely achieved its objectives, such as improving access and supporting economic growth, although some safety benefits were not as high as expected. Additionally, the evaluation found a significant decrease in collisions and a high Benefit Cost Ratio, indicating economic efficiency. However, there were slight increases in noise and air pollution, and the wider economic impacts were not clearly quantifiable. The visual, environmental, and cultural impacts were mixed, with some successful vegetation establishment and mitigation measures, but also negative effects on landscapes, heritage, and biodiversity. The document concludes that while the scheme has generally met its goals and provided value, further evaluation is recommended to address certain aspects, including ongoing environmental monitoring. **This summary was written by an AI model and therefore should not be considered a definitive summary of the report.
