Re the Bay Bridge: Did I Mention?
Friday, August 29th, 2008That, in addition to them having 1 eastbound lane on the eastbound bridge closed for the next 10 weeks, apparently, when it rains, or thinks it going to rain, they are going to suspend the 2-way traffic on the westbound bridge (which means the eastbound traffic goes from 2 lanes to 1, total).
I may end up with round-trip commutes. . . i.e. leave work. . . take the bus to Kent Narrows. . . don’t get off the bus, just turn around and ride it back to D.C. . . . .
BTW: Today is the Friday before Labor Day weekend, traditionally an excessively high volume traffic day heading east. Its raining and expected to rain all day. Any bets on when I’ll get home?
Their notice:
SIGNIFICANT DELAYS EXPECTED AS SAFETY ENHANCEMENTS ARE MADE TO BAY BRIDGE
Labor Day Beachgoers Urged To Travel Off Peak, Use Alternate Route
DO NOT USE SERVICE ROADS TO REACH THE BRIDGE
Construction Could Take Up To 10 Weeks To Complete
Starting today, the right lane of the Bay Bridge’s eastbound span will be closed continuously as work begins to strengthen the parapets (or barriers) lining the side of the bridge. The first section to be modified is near the Eastern Shore side of the span. Pending results of the ongoing testing, potential repairs to other sections of parapet on the eastbound span are possible and could take up to 10 weeks to complete.
“Our annual inspections, that go above and beyond federal requirements, confirm that the Bay Bridge is safe,” said Transportation Secretary and Maryland Transportation Authority (MDTA) Chairman John D. Porcari. “Since the Aug. 10 incident, we have been aggressively assessing bridge operations and structural elements. In-depth testing done to date shows that improvements can be made to strengthen the parapet. Out of an abundance of caution, we want to execute these modifications immediately.”
During the right-lane closure, the posted speed limit on the eastbound span will drop to 40 mph at all times. Two-way traffic will operate as needed on the westbound span to provide two eastbound travel lanes. Commuters will still have three lanes westbound during morning rush hours, as will travelers returning from the Eastern Shore on Sundays and Labor Day Monday.
“The reality is that diminished capacity will lead to delays, particularly during the upcoming Labor Day weekend, but the safety of our motorists, employees and contractors is our top priority,” said MDTA Executive Secretary Ronald L. Freeland. “We’re asking our bridge commuters and local residents to work with us again during these modifications. We’re also encouraging Labor Day beachgoers to use alternate routes and avoid the Bay Bridge this weekend, if possible. Drivers should plan their trips by calling 1-877-BAYSPAN (229-7726) and logging onto baybridge.com.”
The MDTA began today’s repairs after ultrasonic and ground penetrating radar (GPR) testing of the parapet in the right lane near the Eastern Shore indicated corrosion of reinforcing steel bolts encased in the concrete barrier.
(Now I really feel safe crossing this twice a day!)
“The repairs we are starting today will restore the strength of the parapet,” said MDTA Chief Engineer Geoffrey V. Kolberg. “The corrosion is a direct result of voids in the center of the concrete parapet, where moisture has become trapped. If our ongoing testing identifies other parapet areas in need of strengthening, immediate corrective action will begin and could take up to 10 weeks for such repairs.”
Strengthening of the parapet involves bolting an L-shaped steel anchor strap (or bracket) to the parapet and to the bridge deck and bolting a double steel w-beam (or guardrail) to the parapet. Design of a permanent repair to the parapet is underway.
During the lane closure, trucks wider than 12 feet will be prohibited from traveling the bridge in the eastbound direction and must use an alternate route. The restriction includes trucks that have been issued blanket permits.
P.S. Since I have been working in D.C. I have estimated that I have now crossed the William Preston Memorial Bridge (aka Chesapeake Bay Bridge) 1470 times, not counting social visits to friends and family, shopping trips, and any trips pre-Oct. 29, 2005. I’m still not quite used to crossing it, tho its easier to ignore, most days. Except when they tell you the tiny barriers that are on the side of the bridge WONT. HOLD. YOU. IN. Geez. Thanks.
