(AP) - Records from the state Department of
Transportation show that state bridge inspectors noted rusty gusset
plates on the Winona Interstate Bridge as early as 2006, a
newspaper reported on Thursday.

      The corroded plates were cited as the reason behind the bridge's
closure earlier this month. At that time, MnDOT officials said no
red flags were noted in prior inspections, and that gusset plates
weren't closely examined.

      But the Winona Daily News obtained records showing that in 2006
and 2007, inspectors did examine those plates and found "advanced
corrosion." 

The documents also say that rusty holes were found in
gussets on Pier 21 of the bridge -- that's the same pier where
inspectors shattered plates with hammers in an inspection this
month.

      MnDOT officials now say those reports didn't spark action
because gussets weren't considered a critical bridge component
until recently. Failed gusset plates may have contributed to the
collapse of the Interstate 35W bridge on Aug. 1.

      But at least two state lawmakers said the reports on the Winona
bridge and on the I-35W bridge show a pattern where MnDOT officials
deferred necessary maintenance.

      "All we have is a whole stack of pages documenting problems,
and we have no clue whether anybody did anything about it," said
Sen. Sharon Erickson Ropes, DFL-Winona.

      Sen. Jim Carlson, DFL-Eagan, said the Winona bridge reports
reminded him of issues raised in the Gray Plant Mooty report, which
legislators commissioned to investigate the collapse of the I-35W
bridge. That report suggested that budget woes may have led MnDOT
to ignore warnings and defer bridge maintenance.

      "There were things that were mentioned for years and years, and
they were not addressed," Carlson, who is also a mechanical
engineer, said of both the I-35W and the Winona bridges.

      In the prior reports on the Winona bridge, inspectors noted
missing rivets, rust forcing gussets apart and heavy section loss
to corroded plates. MnDOT crews reinforced a single faulty gusset
in 2000, according to the reports.

      Inspectors "have been noticing corrosion and pack rust on that
bridge for awhile," said MnDOT bridge inspector Eric Evens, who
evaluated the Winona Bridge in 2006 and wrote one of the reports.

      MnDOT structures engineer Craig Falkum reviewed the 2006 and
2007 reports and said the rusty gussets were flagged as a problem,
but not as a "critical" concern, even though corrosion had
worsened noticeably in the past two years.

      But Evens said those findings came before the collapse of the
I-35W bridge; now, the National Transportation Safety Board has
directed states to pay more attention to gusset problems.

      "In the light of the bridge failure, things are looked at
differently," Evens said. "Gusset plates got a lot more attention
now than they did then."

      Sen. Steve Murphy, DFL-Winona and chairman of the Senate
Transportation Committee, said doesn't want to blame engineers or
inspectors because engineers had "finite resources to take care of
a lot of problems."

      The Legislature passed a $6.6 billion transportation package
earlier this spring that may ease the financial strain on MnDOT,
Murphy said.

      "Hopefully we've improved the system fiscally to where repairs
can take place before things like this occur," Murphy said.

      Traffic on the Winona Interstate Bridge will be limited to one
lane Thursday and Friday from 9 a.m. to 3:30 p.m. as Minnesota
Department of Transportation crews inspect the structure. Once the
two-day inspection is done the bridge will be reopened to two
lanes.
