Low water crossings.

Authorizes a local county road and bridge board to undertake low water crossing projects. Requires the commissioner of the department of transportation (department) to ensure that the department makes information available to county boards of commissioners and county highway departments about funding from federal and private sources that might be available to the counties for low water crossing projects. Amends the law on the local road and bridge matching grant fund: (1) to allow grants to local units to be used for low water crossing projects; and (2) to provide that funds allocated for grants to local units having a population of less than 50,000 can be used to make grants to counties below the population limit as well as to municipalities located in counties that are below the population limit.
