in between
The calendar says it's summer but the flowers seem to be between seasons. The bright colors of spring have faded away, the summer blossoms are not yet in full bloom.
Sometimes fallen flowers can be as beautiful as those that are still in bloom.

at the airport
This piece of art jumped out at me as I walked out of the gate area at the Philadelphia International Airport last week. There were a sea of people walking with me then. This morning the terminal hallway was close to empty, allowing me to capture an image.
Philadelphia artist Isaac Tin Wei Lin is known for his use of colorful, pattern-filled abstractions and cut-outs of large-scale cartoon cats and totem-like hieroglyphs. Lin often combines all three components by printing repeated patterns on multiple sheets of paper and pasting the patterned paper onto the wall to create a mesmerizing backdrop for his larger than life, upright-walking cats and abstract vertical letterforms.

Tinicum Marsh
I've driven by the sign for the John Heinz National Wildlife Refuge at Tinicum many times without stopping (as I was usually headed for a flight at Philadelphia International Airport). I always wondered what was there; luckily my sister wondered too. It was a hot, humid, and sunny day for a wander, but wander we did.
What a gorgeous place! I'm looking forward to returning again - and I'm so glad there were people who fought to preserve this marsh.

purple (again)
Purple flowers keep calling to me, jumping into my camera. I've always been fascinated by the detailed flowers of clematis and by the plant's ability to climb.

a balancing act
I'm continuing to keep an eye on the Memorial Bridge project web site both to watch for the bridge opening date and to satisfy my curiosity about the remaining work.
I find it simply amazing that the weight of the center span is balanced by that of the counterweights, especially given the weight of the span at 2,500,000 pounds. The numbers are "boggle the mind" big!
As I look at the screen shot from the Memorial Bridge webcam I see that the center span appears to sit a little higher than the fixed spans. I wonder if that is the final resting spot of the span; I guess I should ask!
balancing, center span against counterweights With all three spans now in place, the Memorial Bridge looks virtually complete. And if it were a fixed bridge, that would be true. But the final phase, making the myriad of interrelated adjustments needed for the lift span to run smoothly, is highly complex.
On Sunday, June 30, as reported earlier, the center lift span will stay in the down position beginning at 9:30 pm until 2:00 pm on Tuesday. This is necessary for the sheaves (pulleys) to be adjusted to their final position and bolted into place, allowing the bridge to move up and down smoothly.

At the same time, AWC is in the process of balancing the weight of the 2,500,000 lb center span with the weight of the counterweights. Stephen DelGrosso, AWC Project Manager, says, “The tolerances required for the lift mechanism are very tight, so multiple adjustments need to be made on all systems. This functional testing is an important part of the work remaining.” He explained that even after a lift bridge is opened to vehicle traffic and is on a regular lift schedule, standard procedure is to continue to monitor and adjust the lift mechanisms as needed.

response to my question about the "down" position of the bridge
My question: As I look at the bridge via the Portsmouth webcams (with the center span down) it appears that the center span is slightly higher than the fixed spans. Is it, or is that an optical illusion? If it is, is that the expected final down position?
response from Memorial Bridge PR:
The center span is currently resting on temporary bearings that are 5.75 feet higher than the full down position. So, your eyes are not playing tricks on you! This current position allows the workers to have easier access to the control rooms and allows for more clearance for recreational and fishing vessels that need to pass under the bridge.
