Henry David Thoreau (a local hero) said that he would “require of every
writer, first or last, a simple and sincere account of his own life.” So I
will start with the why of my voyage and then illustrate the how. The
Longfellow Bridge became a waypoint in my life in the summer of 1967. I was
a student at Northeastern University in Boston studying Philosophy somewhat
haphazardly. I was living with my roommate Greg on Marlborough Street not
far from the Boston landfalls of the Longfellow Bridge to the East and the
Harvard Bridge to the West. The Longfellow Bridge is also known as the
Pepper Pot Bridge due to its four iconic towers. Once we discovered that the
door of one ‘pepper pot’ was actually unlocked probably due to vandalism. We
entered the door and found a descending stair leading to a catwalk that
crossed to the ‘pepper pot’ on the opposite side. Having pulled off that
caper we set our sites on a more ambitious goal.We decided to cross the
Charles River on the underside of the bridge!
A quick survey revealed that the bridge consisted of stone faced pillars
joined by open steel girders formed into arches. The girders were standard
“I” beams whose lower flange would afford footing and whose upper flange
would provide handholds. The pillars each had a surrounding ledge just above
the water line. This combination would allow us to sidestep along the side
of each arch and around each pillar. Putting those two maneuvers together we
easily crossed the quiet, though highly polluted Charles River.
Now 55 years later, I was determined to cross under the bridge on Nano, my
Ranger Tug 27. So much for the why, let’s look at the how. We were docked at
the Constitution Marina in Charlstown, Mass. Since Nano is only 12 feet high
with a 3 foot draft, we passed easily under two bridges over the Charles
River where it dumps into Boston Harbor. Our first obstacle was the Gridley
Locks. In the picture you can see a boat similar in size to Nano entering
one of the two smaller locks. Once out of the lockup we easily passed under
two more bridges including the new iconic suspension bridge shown in the
background of the photo. We waited for the commuter rail bridge that
services North Station underneath Boston (“Your Name Goes Here” for a large
fee) Garden to open for our passage.
Charles River Dam was built by the U.S. Army Corps of Engineers. The structure also includes the “Colonel Richard Gridley Locks”, named for General George Washington’s first army engineer. Built and operational in 1978, the three locks can be crossed by pedestrians as well as bicyclists. It is part of the popular Boston Harborwalk. The dam contains three individual locks, with one wider than the other two to accommodate the occasional passing of a larger vessel. The structure also includes a fish passage. Six diesel-powered, 2700 horsepower turbo-charged engines drive six pumps with a combined capacity of about 3.7 million US gallons per minute or 8140 cubic feet per second.

Once through the railroad bridge we approached the Graigie Canal. This short
canal is the remnant of one of the locks build as part of the earlier
Charles River Dam. The other two are covered over by the Boston Science
Museum. There are two bridges over this canal but only one needed to open
for us as you see in the photo. Actually this is photo shot on the way back
since I wanted to include this long distance view of the Bunker Hill
Monument.

We left from the Cambridge side of the Charles River near MIT inching along
walking a tight cable with our hands over our heads. As we passed the first
few arches the cables slowly diverged. At about the fourth or fifth arch,
Dick informed us that he could go no further being the shortest of the
three. Not only could he not proceed, but he could not safely return either.
What to do? Aha! Use the rescue gear! Greg and I returned to the starting
point and walked out on the sidewalk until we were over our waiting buddy.
We lowered the rope over the handrail, swung it back a forth into Dick’s
anxious hands, and pulled him up over the side of the bridge safe and sound.
Once Nano had crossed under the Harvard Bridge my mission was complete save
for the return trip which was completed without incident.
Not bad for first post.
ReplyDeleteFYI the Longfellow is also known locally as the Salt and Pepper bridge for obvious reasons. Nice job on the narrative. Dick
ReplyDeleteAs I recall, the night we toured 'The Bridge' towers and were contemplating an undercrossing of, one of us (I think it was me, but wouldn't swear to it), using the famous 'Red Rope', repelled down the outside of the tower to its base just above the water line to inspect the small ledge that ran around the base. That ledge was about 8" wide and slightly pitched toward the water. Traversing the ledges (7 in all I think) was the most difficult and dangerous part of the crossing as there was nothing to hold onto. Also, as the base above the ledge was curved (see Paul's 1st photo of The Bridge above) away from the upper part of our bodies, there was little other support for balance. One misstep or slip and you were in the water - and if you didn't drown, a stint at the Charles River water pollution detox center would be in order. I'd like to think we were the only one to have pulled off this undercrossing, but I remember Paul recounting that some acquaintances of his had done this near the end of WWII. A motto for our exploits should have been "We will leave no bridge undercrossed". Very much enjoyed the blog Paul - thanks.
