GRAND ISLAND BRIDGES: Structures are in need of repairs
When it comes to the Grand Island bridges, there is more work to be
done.
According to the state Thruway Authority, repairs are scheduled on both the
North Grand Island and South Grand Island bridges over the next five years. The
work will include substructure repairs and deck replacements on all four
bridges.
The work is being done in an effort to bring the bridges back into good
condition. Grand Island’s aging bridges did not garner good ratings during
their last inspections.
According to the Thruway Authority, the South Grand Island bridge northbound
received a condition rating of 3.84 out of seven during its last inspection in
November 2006. The southbound bridge received a 3.91 rating during the same
inspection.
The North Grand Island bridges didn’t score much better. Its northbound bridge
got a 3.98 condition rating in a November 2005 inspection; the southbound bridge
got a 3.78 rating.
Bridge condition ratings range from one to seven. Both bridges ranked just below
the “poor” classification.
Bridge conditions have been on the minds of the public in the wake of
Wednesday’s collapse of Minneapolis’s Interstate 35W bridge. The U.S.
Secretary of Transportation Mary E. Peters has now asked states to inspect
similar steel deck truss bridges.
“Even though we don’t know what caused this collapse, we want states to
immediately and thoroughly examine all similar spans out of an abundance of
caution,” Peters said in a press release.
Gov. Eliot Spitzer said similar bridges must be inspected within 30 days.
According to the Federal Highway Administration, there are 756 steel deck truss
bridges, like the Minneapolis and Grand Island bridges, in the United States.
Thruway Authority spokeswoman Betsy L. Graham said the North Grand Island
bridges have been under inspection since June. Once that inspection is complete,
the South Grand Island bridges will be under scrutiny.
“The (Thruway Authority) follows a very stringent and thorough bridge
inspection program, as mandated by federal and state guidelines, and will
continue to do so,” Graham said. “At least every two years, every bridge in
the state is inspected as part of the bridge inspection program. Additionally,
interim inspections take place every year on the Grand Island bridges.”
Graham said work has been completed and scheduled on both sets of bridges to get
them in better condition as part of a $62 million project under the
authority’s capital plan. So far, $10 million has been spent on general
construction and steel repairs on the South Grand Island bridges and $1.4
million has been spent to place sidewalks on the North Grand Island Bridge
northbound.
The authority is currently working on a $1.5 million sidewalk rehabilitation
project on the South Grant Island Bridge southbound. The work is expected to be
done by the end of the year.
More projects are planned for both bridges for at least the next five years.
Later this year, a $30 million nighttime deck replacement will begin on the
South Grand Island Bridge northbound in conjunction with substructure work for
the entire bridge. The project is expected to be completed in late 2009. A deck
replacement project is “being slated as priority” in 2012, Graham said, and
substructure repairs would likely be done at that time.
When it comes to the future of the bridges, Graham said expansion has been
recommended. In a 2004 report by Bergmann Associates, the South Grand Island
bridges currently need a third lane in both directions to handle traffic through
2020. Another lane in both directions would need to be added onto that after
that year. The report also said a third lane would be needed on the North Grand
Island bridges by 2010 to accommodate traffic through 2030.
Graham said the authority estimated it would cost about $500 million to replace
all of the Grand Island bridges completely.
