Michigan Engineers' Resource Library (MERL) is a software suite created by the Center for Technology & Training (CTT) that helps transportation engineers create road and bridge project estimates, enter and analyze bids for local jobs, and track daily postings and payment estimates. In addition, MERL provides engineers with access to various Michigan Department of Transportation (MDOT) resource documents.
MERL is free of charge to any Michigan local agency and their consultants. MERL may be downloaded from.
