Minneapolis ? The mayor and a key state lawmaker on Monday cautioned that the Minnesota transportation officials’ swift timetable to replace the collapsed interstate bridge could overlook safety and the unique elements necessary to make it a memorial.

“I believe a large number of people want this bridge to symbolize the rebuilding of a community in some way,” Mayor R.T. Rybak told The Associated Press. “That does not seem to be a significant part of MNDOT’s goal at this point.”

On Tuesday, Department of Transportation officials were to release preliminary designs for the new bridge, which the agency has said it wants to build five lanes in each direction by the end of next year. The old bridge had four each way.

While politicians wrangled over the future bridge, recovery work continued at the failed bridge. Navy divers returned to the water about 6:15 a.m., still seeking the bodies of four missing motorists presumed killed in the collapse. Nine people are confirmed dead.
