This technical paper presents a comprehensive evaluation of non-traditional safety measures implemented during the construction of a reserved lane on Highway 15 in Quebec, specifically between Blainville and Mirabel. The study focuses on the innovative use of painted shield pavement markings as a visual aid to enhance driver navigation and safety during the relocation of exit ramp 35. Drawing inspiration from historical practices such as those on U.S. Route 66, the painted shields were strategically placed to compensate for the temporary removal of overhead signage. The effectiveness of these measures was assessed through collision data analysis, video surveillance, and a survey conducted among provincial police officers. Results indicate a positive impact on road safety, with a majority of respondents acknowledging the usefulness of the painted shields in reducing collisions. Additionally, the integration of a cloud-based document-sharing system improved coordination between the construction team and the law enforcement. The findings support the broader adoption of painted pavement markings and digital collaboration tools as effective strategies for enhancing safety and operational efficiency on highway construction sites.
