ASCE Update on I-35W Bridge Collapse
The anti-icing system used on the I-35 W bridge sprays an anti-icing chemical onto the concrete bridge deck when sensors and information from the Road Weather Information System tell it that hazardous conditions are imminent. The anti-icing chemical is potassium acetate. The sensors are ground and deck surface sensors that measure temperature and moisture, and sensors to measure ice formation. The Road Weather Information System are weather stations that measure air temperature and have optical precipitation sensors to detect rain, snow, and sleet. Read the report of the anti-icing system at:

The Minnesota State Senate Transportation Budget & Policy Division and the State House Transportation Finance Division held a joint public hearing on August 15, 2007 on the I-35 W bridge collapse. During that hearing, the members of the Divisions asked Minnesota DOT (MN-DOT) many questions that MN-DOT needed time to respond. MN-DOT has responded to those inquiries and a letter from MN-DOT summarizing the questions and providing the answers is available at:
http://www.dot.state.mn.us/i35wbridge/legislative/Aug15hearing-followup-letter.pdf
MN-DOT has provided some additional information about the Municipal Consent process. This is the law in Minnesota that requires MN-DOT to obtain "municipal consent" from the municipality involved when the highway project alters access, increases or reduces traffic capacity (for example, increasing or reducing the number of traffic lanes), or requires acquisition of permanent right-of-way.

The Federal Emergency Management Agency (FEMA) has issued a press release concerning the I-35 W bridge collapse and federal aid programs that are available. In the press release FEMA states that "Initial FEMA-administered aid is limited to $5 million." Read FEMA's press release at: http://www.fema.gov/news/newsrelease.fema?id=38970.
In an unrelated, but important development, MN-DOT closed a bridge today. The Highway 11 bridge over the Red River sharing the border with North Dakota was closed "after a crack was discovered in a support bracket for a girder during an inspection...".

ASCE Update on I-35W Bridge Collapse
http://www.ci.minneapolis.mn.us/mayor/docs/35W_state_princ.pdf
Minnesota DOT (MN-DOT) has hosted several public meetings on the new I-35W replacement bridge project and has posted handouts from these meetings. MN-DOT has also provided an update on the permits for this project. To date, permits have been received from the Minnesota Department of Natural resources and the U.S. Army Corps of Engineers. Permits are pending from the U.S. Coast Guard and the Minnesota Pollution Control Agency. The handout in the link below provides a full listing of the permits and describes that the additional lanes on the new bridge to accommodate transit may not be for light rail, but could be for a bus rapid transit lane, High Occupancy Toll (HOT) lane, High Occupancy Vehicle (HOV) lane, or some other form of managed lane.

MN-DOT Public Open House to Discuss Design-Build Project to Replace I-35W Bridge
MN-DOT's proposed plans for the new I-35 W bridge include 10 lanes for the bridge (up from eight lanes on the previous bridge) with one lane in each direction possibly accommodating transit. Lt. Governor Carol Molnau and Metropolitan Council Chair Peter Bell have sent a letter to Governor Tim Pawlenty describing their assessment for the Governor of the light rail possibility. Their letter states: "At your direction, we have completed our preliminary assessment of the potential for reconstructing the I-35 bridge in a manner that could incorporate a light rail line. For the reasons that follow, we have concluded that the inherent disadvantages of including LRT do not justify the expense and delays that would result from further study."

Additional Funds for Emergency Repairs and Reconstruction of the Interstate I-35 Bridge
Upkeep Of Security Devices A Burden
Monday, August 13, 2007--In 2003, the FBI used a $25 million grant to give bomb squads across the nation state-of-the-art computer kits, enabling them to instantly share information about suspected explosives, including weapons of mass destruction.
Four years later, half of the Washington area's squads can't communicate via the $12,000 kits, meant to be taken to the scene of potential catastrophes, because they didn't pick up the monthly wireless bills and maintenance costs initially paid by the FBI. Other squads across the country also have given up using them. See Washington Post article by Mary Beth Sheridan.

New York Company Indicted in Collapse of Big Dig
BOSTON, Aug. 8 — The supplier of the epoxy that federal officials have blamed for the collapse of a Big Dig tunnel was indicted today in the death of a motorist crushed by falling ceiling panels.
The company, Powers Fasteners Inc., was charged with one count of involuntary manslaughter. It is the first criminal charge in the tunnel debacle, which killed Milena Del Valle, 38, in July 2006 as she was on her way to the airport. Her death ignited an uproar over the safety of the $15 billion Big Dig, the most expensive single public works project in American history.

Problems with Minnesota bridge noted twice since 2001:
http://www.cnn.com/2007/US/08/02/bridge.structure/index.html#cnnSTCText
Here is the MnDOT 2001 Report:
http://www.lrrb.gen.mn.us/PDF/200110.pdf
A 2001 study conducted by the Minnesota Department of Transportation found "several fatigue problems" in the bridge's approach spans and "poor fatigue details" on the main truss. The study suggested that the design of bridge's main truss could cause a collapse if one of two support planes were to become cracked, although it allowed that a collapse might not occur in that event. But, the study concluded, "fatigue cracking of the deck truss is not likely" and "replacement of the bridge ... may be deferred."
Two years ago, the U.S. Department of Transportation's National Bridge Inventory database said the bridge was "structurally deficient." The Minneapolis Star Tribune quoted Jeanne Aamodt, a spokeswoman for the Minnesota Department of Transportation, as saying the department was aware of the 2005 assessment of the bridge. The bridge received a rating of 4 on a scale of 1 to 10. A bridge receives a rating of 4 when there is "advanced section loss, deterioration."

National Hurricane Center-Recommended Storm Surge Safety Actions
- Minimize the distance you must travel to reach a safe location; the further you drive the higher the likelihood of encountering traffic congestion and other problems on the roadways.
- Select the nearest possible evacuation destination, preferably within your local area, and map out your route. Do not get on the road without a planned route, or a place to go.
- Choose the home of the closest friend or relative outside a designated evacuation zone and discuss your plan with them before hurricane season.
- You may also choose a hotel/motel outside of the vulnerable area.
- If neither of these options is available, consider the closest possible public shelter, preferably within your local area.
- Use the evacuation routes designated by authorities and, if possible, become familiar with your route by driving it before an evacuation order is issued.
- Contact your local emergency management office to register or get information regarding anyone in your household whom may require special assistance in order to evacuate.
- Prepare a separate pet plan, most public shelters do not accept pets.
- Prepare your home prior to leaving by boarding up doors and windows, securing or moving indoors all yard objects, and turning off all utilities.
- Before leaving, fill your car with gas and withdraw extra money from the ATM.
- Take all prescription medicines and special medical items, such as glasses and diapers.
- If your family evacuation plan includes an RV, boat or trailer, leave early. Do not wait until the evacuation order or exodus is well underway to start your trip.
- If you live in an evacuation zone and are ordered to evacuate by state or local officials, do so as quickly as possible. Do not wait or delay your departure, to do so will only increase your chances of being stuck in traffic, or even worse, not being able to get out at all.
- Expect traffic congestion and delays during evacuations. Expect and plan for significantly longer travel times than normal to reach your family's intended destination.
- Stay tuned to a local radio or television station and listen carefully for any advisories or specific instructions from local officials. Monitor your NOAA Weather Radio.
- For more tips, see: http://www.nhc.noaa.gov/HAW2/english/storm_surge.shtml

With Financial Tactic, Corzine Would Keep Turnpike Public, Toll Increases and All
Who knew that the New Jersey Turnpike, the state’s congested artery that commuters love to hate, was so beloved?
In the months since Gov. Jon S. Corzine began exploring ways to capitalize on the state’s assets and pay off billions of dollars in debt, a coalition of legislators, environmentalists and drivers have come out against any plan that would include leasing the Turnpike and the Garden State Parkway to private investors.
Long before Mr. Corzine could unveil a proposal, these opponents warned that private investors would increase tolls to unreasonable levels, let the roads fall into disrepair and stymie any efforts by the state to expand its highways.
Yet Mr. Corzine, a shrewd former investment banker, appears to have found a more palatable solution that lets the state raise billions of dollars while keeping the highways in public hands. At a news conference last week, Mr. Corzine said he and State Treasurer Bradley I. Abelow were considering “an entirely different kind of proposal” that involved creating a public benefit corporation.
One option is for the New Jersey Turnpike Authority to raise tolls and divert only the increased revenue to a newly formed public corporation, which would then issue bonds backed by that money. The amount of the bonds would be based on the value of the toll increases.

Some of the most celebrated levee repairs by the Army Corps of Engineers after Hurricane Katrina are already showing signs of serious flaws, a leading critic of the corps says.
The critic, Robert G. Bea, a professor of engineering at the University of California, Berkeley, said he encountered several areas of concern on a tour in March.
The most troubling, Dr. Bea said, was erosion on a levee by the Mississippi River Gulf Outlet, a navigation canal that helped channel water into New Orleans during the storm.

N.O. Leadership lacking, report says
Housing shortage also hindering recovery, it says
Times-Picayune, April 25, 2007, By Bill Barrow
BATON ROUGE -- A failure of local leadership and a lack of affordable housing are primary reasons that New Orleans trails many other Gulf Coast communities in storm and flood recovery, according to a new report.
The report, issued jointly by the Public Affairs Research Council of Louisiana and the Rockefeller Institute of Government, is the second in an ongoing analysis of 22 locales that were affected -- in some cases positively -- by Hurricanes Katrina and Rita.
Overall, the report describes regionwide recovery as "uneven," with the progress of each local area dependent on how effective leaders have been in making decisions; how badly its business and economic infrastructure was damaged; and how quickly it has been able to get state and federal aid.

The future competitiveness of the infrastructure system presents an engineering leadership challenge
In this context, there are two readily-apparent ways for engineers to effect change. First, engineers need to position themselves better by seeking public office, which would provide them with proximity and access to the legislative process. Second, in order to help Congress to better understand technology transfers and complex scientific principles before implementing new policies, the engineering discipline should actively recruit and pitch its professionals for placement on lawmaker and committee staffs. This second tactic is likely to require a cultural shift in the engineering profession. Talented engineers will not readily pursue alternative but important career paths if they think that their work will be dismissed or devalued by the profession, including its societies and licensing boards. Likewise, lawmakers and committees are unlikely to understand the benefits of having engineers on their staffs and deferring to their judgment on important social issues without a significant public relations campaign. The stakes are high enough, however, that extreme measures are necessary.

'Lautenberg Language' On Chemical Security Passes Senate
States' Right To Adopt Strong Chemical Security Laws Like NJ's Protected
On Thursday, March 29, 2007, the Senate passed the FY 2007 Supplemental Appropriations Bill with a provision authored by Sen. Frank R. Lautenberg (D-NJ) to block the Bush Administration's plan to preempt state chemical security laws.
The "Lautenberg language" overcame a vigorous campaign from chemical industry lobbyists who fought the ability of states to enact stronger laws than the federal government.

New chemical rules won't override states
"If a state measure to regulate security at high-risk facilities does not conflict with, interfere with, hinder, or frustrate the purpose of DHS's regulations, it would not be pre-empted," Chertoff wrote. Lumpkin writes that Lautenberg was not mollified. "Rather than let New Jersey and other states move forward defending our communities from attacks on our chemical facilities, the Bush administration is trying to freeze us in our tracks," said Scott Mulhauser, a spokesman for Lautenberg.
