(Reuters) -Mazda Motor will probably have to temporarily move shipments to another port from Baltimore to avoid delays, the automaker's CEO said in a CNBC interview.

The Port of Baltimore ranks first in the U.S. for volume of autos and light trucks and farm and construction machinery handled and a cargo ship crash into the Francis Scott Key Bridge in March has restricted shipments.

However, CEO Masahiro Moro said Mazda does not currently expect a big impact from the port shutdown.

U.S. automakers General Motors (NYSE:GM) and Ford (NYSE:F) have said they would reroute the affected shipments.

Most of the traffic remain suspended, though some terminal operations outside the affected area have resumed.

Earlier this month, Mazda posted a near 13% rise in first-quarter U.S. sales to 100,103 units from a year earlier.
