List

Date	State	County	Bridge Name	Bridge Type	Problem Location	Problem Description	Detailed Comments	Suggestions
11/24/2012	Massachusetts	Suffolk	Grand Junction Railroad Bridge	Water or natural body crossing	Over Charles River connecting Boston and Cambridge	Facility Condition (cables, tower)	The 90-year old freight bridge will be closed down for two weeks due to crossbeams that need to be replaced after visual inspection revealed movement in its trusses.	Routine inspection should be regularly conducted especially on aging infrastructures among all railroads involved, here being MBTA, CSX, and Amtrak. Advanced technology in sensors should be applied as opposed to error-prone human visual inspection.
03/20/2012	Connecticut	Fairfield	Veterans Memorial Bridge	Water or natural body crossing	Over Housatonic River	Facility Condition (cables, tower)	A nearly 60-year old bridge considered structurally deficient shows aging rivets holding down iron girders. Over 300 bridges throughout the state maintain such aging rivets.	Work should be aggressively done to remedy this problem such as replacing worn rivets with high-strength steel bolts. Needed funds should be allocated proactively to prevent future disasters. A crisis should not warrant policymaking.
02/19/2012	Minnesota	Hennepin	Sabo Bridge	Pedestrian or bicycle crossing	Over Hiawatha Avenue (Hwy 55)	Facility Condition (cables, tower)	Metal plates connecting a pair of cables to the bridge broke and fell with more faulty plates found later.	After repair, investigate if the damage was caused by faulty design, aging structure, or inability to handle traffic load.
01/23/2012	Texas	Tarrant	West Seventh Street Bridge	Water or natural body crossing	Entire bridge over Trinity River	Facility Condition (cables, tower)	The 99-year old bridge that carries 12,000 vehicles per day and set to be replaced in 2013 shows obvious signs of deterioration with metal rods poking through surface, flaking off concrete, minor cracking, and material loss. And officials are not taking measures to mitigate current issues.	Entire process for rehab moves at snail's pace. Federal and state funding needs to be secured on fast track since situation deals with safety of motorists. New construction still dominates funding over rehab or replacement projects which should be changed. Lastly, the state should begin contracting work with powerhouse Texas construction firms like KBR and Fluor Corp.
12/10/2011	Kentucky	Jefferson	John F. Kennedy Memorial Bridge	Water or natural body crossing	I-65 bridge over Ohio River connnecting KY and IN	Facility Condition (cables, tower)	Bridge rated fair by state inspectors but still carry vulnerable conditions: a cracked roadway, damaged joints, downgraded weight-bearing superstructure beams.	Use this situation as a prime opportunity to mobilize the private sector and university innovation for bridge monitoring and rehabilitation. Use products like Resensys and other IT systems for wireless sensors. Develop contracts now to deploy crews for near future maintenance work.
11/25/2011	California	San Francisco	San Francisco-Oakland Bay Bridge	Water or natural body crossing	Eastern span of bridge	Other issues	Delivery of eastern span replacement project has undergone several hurdles: construction uncertainty of innovative design, inspectors of structural integrity, rising cost of steel and concrete, and state legislature approval of funding.	For complex projects like this one, all key players across the life-cycle should be coordinated. Also, better project management, leveraged initial capital costs, and inventory of materials. State policymakers should be regularly briefed on progress. This may reduce delays.
