While work on the Roslyn Viaduct has been bedeviled by off-again, on-again nighttime closures, a survey by Road & Bridges magazine has named the "Viaduct Replacement" as one of the Top 10 Bridges in America for the past year.

"The announcement of this year's Top 10 Bridges list coincides with a renewed national focus on our country's bridges and the dramatic funding shortages for infrastructure projects," said Bill Wilson, editorial director of Roads & Bridges and creator of the list. "Public safety considerations, along with the complexities of project specifications and traffic impact, made the selection of this list especially difficult. Each one of these projects overcame testy challenges and answered the call of providing efficient transportation."

The Roslyn Viaduct placed 10th on the list, but the fact that it did make it is an achievement.

The Top 10 Bridges list for 2007 is as follows:

No. 1: Replacement of 1-10 over Escambia Bay, Pensacola, FL;

No. 2: U.S. 90 Bay St. Louis Bridge, Bay St. Louis, MS;

No. 3: John James Audubon Bridge, LA;

No. 4: Missisquoi Bay Bridge, Alburg-Swanton, VT;

No. 5: Route 15 over the Housatonic River, Milford/Stratford, CT;

No. 6: Treasure Island Bascule Bridge Replacement, City of Treasure Island, Pinelias County, FL;

No. 7: Bridge over Ohio River and Blennerhassett Island, Parkersburg, WV;

No. 8: U.S. 17 Washington Bypass, Washington, NC;

No. 9: Markham Yard Bridge Reconstruction on Tri-State Tollway, East Hazel Crest, IL;

No. 10: Roslyn Viaduct Replacement, Roslyn.

Design firms, DOT and engineers nominated nearly 60 North American bridge projects, ranging from $42 million to $348 million.

To be considered for the competition, all projects were required to be in the design or construction phase within the past 18 months. Entries were accepted June 2007 to August 2007.

In 2007, demolition of the northern portion of the bridge was completed in March. Installation of the precast pier column segments for the new northern portion of the bridge began in May and continued through the summer. After installation of the pier columns on the portion of the bridge that is east of the waterway, the transport and erection of girder segments began in September 2007.

Currently, during the transition hours of 2 to 3 p.m., 10 to 11 p.m. and 5 to 6 a.m., one travel lane in each direction remains open to allow time to reposition the lanes back into successive reversible lane pattern. According to DOT officials, this reversible travel lane pattern for the Roslyn Viaduct is expected to remain in effect until the spring of 2009.
