Ca­ble pro­ject on Bay Bridge given lo­cal, na­tional awards

Record Observer - - News -

BAL­TI­MORE — The Mary­land Trans­porta­tion Author­ity has re­ceived lo­cal and na­tional recog­ni­tion for its in­no­va­tive ca­ble de­hu­mid­i­fi­ca­tion pro­ject at the Bay Bridge.

The $51 mil­lion pro­ject, the first of its kind in the United States, was com­pleted last year and in­cluded the rewrap­ping and de­hu­mid­i­fi­ca­tion of the main ca­bles and an­chor­ages of the east­bound and west­bound Bay Bridge main spans, the only sus­pen­sion bridges in Mary­land.

“Th­ese awards show Mary­land is a na­tional leader in its use of in­no­va­tion and state-of-theart tech­niques to sus­tain Mary­land’s in­fra­struc­ture for years to come,” said Mary­land De­part­ment of Trans­porta­tion Sec­re­tary and MDTA Chair­man Pete Rahn.

De­hu­mid­i­fi­ca­tion is a cost-ef­fec­tive means of pre­serv­ing main ca­ble systems that has been proven on bridges in Europe and Ja­pan. Twenty sus­pen­sion bridges around the world use de­hu­mid­i­fi­ca­tion systems to pro­tect their bridge ca­bles. De­hu­mid­i­fi­ca­tion systems elim­i­nate mois­ture within air­tight ca­ble wrap­ping, de­liv­er­ing su­pe­rior pro­tec­tion and ex­tend­ing the ser­vice life of the ca­bles.

“It is an honor to have other pro­fes­sion­als learn­ing from our tech­niques,” said Milt Chaf­fee, ex­ec­u­tive di­rec­tor of the MDTA, which fi­nances, owns, op­er­ates and main­tains the state’s eight toll fa­cil­i­ties. “After vis­it­ing the Bay Bridge pro­ject, sev­eral U.S. sus­pen­sion bridge own­ers have in­di­cated to us their plans to in­stall de­hu­mid­i­fi­ca­tion systems on their bridges.”

The MDTA and its pro­ject part­ners, AECOM, Am­mann and Whit­ney and Kiewit In­fra­struc­ture, re­ceived the fol­low­ing awards for the team’s ac­com­plish­ments:
