The construction and maintenance of transportation infrastructure has the potential for significant impact on both the natural and human environment, and management of these activities is a highly complex endeavour. In keeping with its commitment to sustainable development, the ministère des Transports du Québec (MTQ) has produced a guidebook bearing the title L’environnement dans les projets routiers du ministère des Transports du Québec (MTQ Roadway Projects and the Environment – The Guidebook) as an environmental management tool to ensure a more efficient integration of environmental considerations in the roadway infrastructure project planning process. This 39,4 Mb document is available (in French only at this time) from the MTQ Website at the address below: https://www.mtq.gouv.qc.ca/portal/page/portal/ministere/ministere/environnement#documentation The distribution of this Guidebook to private sector design firms, municipal civil servants and other government officials, contractors and construction supervisors will contribute to protecting and enhancing the environment, as it includes numerous field-tested methods and techniques having previously obtained the requisite environmental approvals. This guidebook is destined to become the primary training manual for current personnel and the next generation of roadway designers and builders.
