Connections Study Narrows options for Bridges from 60 Options to 12

At the Stakeholders meeting for the Maine New Hampshire Connections Study, NHTB consultants went over the first round of the "Fatal Flaw Analysis".  This analysis is a process that through a series of reviews is designed to eliminate the options for connecting Portsmouth and Kittery that for one reason or another do not make sense.  In the first round of this analysis only the highest level of analysis is done, to save taxpayer money.  As the second and third rounds continue, the analysis will get more detailed (and more costly), will be done on fewer options, and will continue to eliminate options from the list.

The Fatal Flaw analysis is now through the first round of analysis and has reduced the options to a list of about 12 options.  Five of these options relate to the Memorial Bridge, and the others to the Sarah Long Bridge.

For the Memorial Bridge, the options that remain are:

• Rehabilitate the Bridge (Funding for this option has been applied for under the Stimulus Program)
• Replace the Bridge (Remove the existing bridge and build a new bridge of similar design to replace it)
• Replace with a Bridge downstream from existing bridge (Build a replacement bridge 60 feet East of the existing bridge before removing the existing bridge)
  
• Close and remove the Bridge (leaving no crossing between Kittery, Badgers Island, and Portsmouth)
• Replace the Bridge with a Pedestrian/Bicycle bridge (Remove the Memorial Bridge and build a new span)

For the Sarah Mildred Long Bridge, the options that remain are:

• Rehabilitate the existing bridge
• Replace the existing bridge (remove the existing bridge before building an improved bridge in the same location.
• Build a new bridge 60 feet upstream from the existing bridge before removing the existing bridge
• Replacing the existing bridge with a "mid level" bridge (assumes moving the rail line along with the roadway to the new bridge)
• Replacing the existing bridge with a high level (135') arch span (the rail traffic would remain on the existing bridge)
  

Each of the options for the Sarah Mildred Long bridge could be further expanded to include 2 or 4 lane options, options with or without bicycle and/or pedestrian capability.

To make things more complex try to imagine each of the options for one bridge in combination with the options for the other bridge.  You can see that this is a complex process.

Some of the options that have been considered and thrown out include closing both bridges, building a new bridge (roughly half way between the two existing bridges), building a tunnel, and establishing ferry service.

The next round of analysis should be done in mid December.

Memorial Bridge Limited to 10 Tons - Deteriorating Condition may Improve Chances for Stimulus Funding

As a result of the inspections being conducted on the Memorial and Sarah Mildred Long bridges, the load limit on the Memorial Bridge has been reduced by 50% to 10 Tons.  The major impact of this limitation will be some truck traffic will be diverted, and all fire trucks will be diverted.  This will increase the time needed for Kittery and Portsmouth to respond to fires in one another's primary service areas.  According to Bob Landry at NH DOT, the limitation will not affect 95% of the traffic on the bridge.

As the condition of the bridges continues to deteriorate, the argument for their repair becomes more clear.  One of the major criteria for qualification for TIGER Stimulus funding has to do with the condition of the existing infrastructure.  While the bridge is still safe, given the load restrictions, the declining condition makes the case for repair more evident.

Sarah Mildred Long Bridge Limited to 20 Tons - Condition Worse than reported

During the last few weeks, teams of inspectors have been taking a detailed look at the Memorial and Sarah Mildred Long Bridges to determine their remaining life.  According to NH DOT who has been managing the inspection process, there have been no surprises for the Memorial Bridge, yet.  The Sarah Mildred Long bridge is another story.  In a press release on June 26, Robert Landry from the NH DOT announced the immediate limitation of traffic on the Long Bridge.  While not disclosed in the press release, the obvious conclusion is that significant corrosion was noted on the Long Bridge, more than was expected.  As a result, until emergency repairs are complete, the traffic on the Long Bridge will be limited to 20 tons.  This is the same limitation that is currently on the Memorial Bridge.  

The press release indicated that the load limitations would be limited to three weeks, while repairs are completed.  Further analysis of the inspectors photographs and measurements indicate that the deterioration is worse than originally thought.  At the present time there may be as many as seven of the fixed spans that are affected, rather than the initial indication of only one.  This will mean an extended repair cycle.  NHDOT is working to better understand the implications of this very preliminary information to see whether the load limits are appropriate during the repair process.

The inspection process is still continuing.  The inspectors have taken thousands of photographs of each of the supporting members of the bridges.  They have also taken measurements of the decay and the remaining metal in the beams.  They now need to review all the photos and measurements, enter the data into complex engineering models, and calculate the effective load characteristics of the bridges.  This will take time.  

The results of the inspection to date have shown that on one bridge the corrosion is in more than expected.  The determination of the remaining life of both bridges will come out of the final report of the inspectors.  This is not due until August.  Hopefully Maine will have seen the results and will have made their decision concerning Stimulus funding by the end of June.

Maine Legislation Amended to Level the Playing Field (Somewhat)

LD 736 is legislation recently passed by the Maine House and Senate.  An amendment in this bill originally mandated that Maine place an extension of I-95 in Aroostook county above all other priorities for any and all transportation funding.  Through the efforts of the York County legislators (Dawn Hill in particular), with cooperation from legislators in the Portland area, the bill has been amended to remove the mandatory and emergency language.  This bill as currently amended will level the playing field. 

Thanks to Dawn Hill and the entire York County delegation.

Road Trip to Augusta Moved the Ball Forward

Jon Carter, Kittery Town Manager, led a delegation to Augusta to educate Maine legislators, DOT Commissioner David Cole and Jane Lincoln, Chief of Staff to Governor John Baldacci.  The group included Ben Porter, Susan Tuveson, Helmar and Marsha Herman, Debbie Ronquist, Beth Wheland, Kinley Gregg and Richard Candee.  The legislators were treated to Moe's subs for lunch and listened to Ben Porter's presentation on the Bridge crisis.  We received support from the legislators and commitment to consider our proposal from the executive branch.
