The Michigan Supreme Court Friday handed state transportation officials a victory when it upheld a ruling requiring Manuel Moroun, the owner of the Ambassador Bridge, to rebuild the ramps and approaches leading to the span. The ruling could pave the way for forcing Maroun to conform to designs by the Michigan Department of Transportation.

The Ambassador Bridge is the only bridge to span the Detroit River between the U.S. and Canada. The ruling is part of a larger battle between Maroun and state officials. Both sides are pushing forward with plans to build new spans just a few miles apart on the river to capture traffic on the trade route, the busiest in the U.S.
