The 31 year old Norris Bridge is "Structurally Deficient"
Waiting to hear the $30 million Bridge plan
$30 million Rehabilitation is Complete
We found another reason to push for Bridge Replacement; "Inadequate Design."
The I-35 bridge:
• was built in 1967.
• was one of the last Truss Deck bridges built.
• was only 40 years old when it collapsed.
Other collapsed Truss Deck Bridges:
Upon learning of the I-35 bridge Collapse
One aspect of a Truss Deck design is these bridges are Fracture Critical by nature:
Another $30 Million in Repairs are complete:
$12.8 million & 18 months to complete painting of Bridge
$25 million plan to Rehabilitate the wearing surface; another project.
1998: $30 million in repairs or maintenance
2012: $30 million in repairs or maintenance
2016: $12.8 million in repairs or maintenance
2020: $25 million in repairs or maintenance
Total: $97.8 million in the last 25 years
This does not include money spent on:
This does not include the contracts for Inspections which take a month every year, as required by the Federal Highway Administration [FHWA] since 1968 as a result of the Silver Bridge collapse in Point Pleasant, WV. [note: same design as the Norris Bridge]
We do not really know how much money has been spent to maintain the Norris bridge at a condition just above "structurally deficient" for the last 25 years.
The FHWA mandates "cost effective" maintenance. How do we determine this without total dollars spent and total dollars lost due to impacts?
No matter how much money we throw at the Norris Bridge it ill still be Functionally obsolete, 60+ year old bridge that was not designed to carry the volume or nature of traffic it does today.
