Capital improvement projects to US and Canadian bridges are funded by their dutiful owners, while all regular maintenance and operating costs are a shared expense between the Thousand Islands Bridge Authority and FBCL.  Because of the possibility of impeding traffic flow, major improvement projects involving traffic control are purposely phased to minimize impact on traffic.

The Thousand Islands Bridge Authority operates its bridges and facilities without State, Provincial or Federal funds and does not provide toll revenues to non-bridge operations.
