Uneven Lane no worry for Rider; Barrier Update

This afternoon the far right lane — that will become the shared use path — was blocked by orange cones. Signs posted on the overhead gantries tell motorcyclists the second lane (that will become the breakdown lane) is uneven.

This ambitious person was riding on a motorcycle, and apparently neither the gantries’ message about the road surface nor the road itself bothered him.

Good for him! Take note, drivers who complain about the uneven right lanes.

Because of the orange cones there was traffic — yes, really — on the Westchester approach span. It gave me a chance to see a bit of the new maintenance facility progress. And . . . the concrete barrier was moved so there were still four lanes westbound.

Speaking of barrier, next week crews will start removing the structures that store the Tappan Zee Bridge’s movable barrier and will also replace sections of its concrete barrier — that separates eastbound traffic from the empty lanes — with orange traffic barrels.

I’d like to know what you think.

ICMYI: Link to Opening Ceremony for New Span

Here is one of the stories you’ve been waiting for with photos from last week’s opening ceremony. The above traffic pattern remains in effect until eastbound traffic moves to the new span within a few months.

What you can’t see (and I won’t show) are blisters I got from walking around in socks and steel-toed shoes for four hours. Would I do it again? YES!

More details and photos of the new span in this week’s Rockland County Times.

I’d like to know what you think.

You say One Month, & They say a Different One

Winding down to the finish line yet still behind schedule for the first span to open. Maybe no one really knows as there’s still much work to be done before rubber meets roadway on the new Governor Mario M. Cuomo Bridge.

Weather may be a factor in the delay; however, a nearly-six-month delay is a bit much. “If the Thruway Authority doesn’t have the keys to the new bridge by March or April of 2018, then the contractor will be charged $100,000 per day for each day beyond that,” one source said in 2014. That’s the 62-month mark.

With eight or nine months until next spring, it seems unlikely both spans will open by then. “The bridge will open sometime in 2018,” other reporters and I hear and continue writing. No one is sure when.

You may be able to see some of the new westbound span’s lighting fixtures; not so easy with the upper main span tower’s aesthetic lighting fixtures. Periodic testing is on the way.

There’s also progress at the new maintenance facility in Tarrytown this week and footing and retaining wall construction — that includes galvanized steel sheets — for the new police facility on the south side of the Thruway.

About three-quarters of the eastbound span’s 96 stay cables have been installed, and yes! the eastbound span now has one of its eventual eight overhead gantries.

Another reporter said, “The Tappan Zee Constructors, the group of contractors tasked with designing and building the bridge, also need to stripe the driving surface.”

The consortium is Tappan Zee Constructors not the Tappan Zee Constructors. Further, Tappan Zee Constructors needs not need to stripe the driving surface. No editing prior to publication?

Third Gantry soon added to Westbound Span

This week the third gantry will be installed on the new westbound span. Pretty cool to see the span taking shape. Read more about gantries here.

Sometime this year, maybe in a few months, we’ll be driving on that span.

There’ll be no Rhythmic Bumps on New Bridge

bridge

Driving across the current bridge is sometimes an interactive experience.

Motorists see the construction progress — most noticeably, that self-climbing jump forms were removed from all eight main span towers, revealing their chamfered tops. They can also feel and hear their three-mile trip, thanks to nearly 200 expansion joints that absorb the bridge’s steel and concrete slight expansions and contractions.

No rhythmic bumps on the new bridge, which will have 12 such joints on the westbound span and 11 joints on the eastbound span.

About the overhead gantries:

Intelligent Transportation Systems (ITS) will monitor conditions on the new spans and automatically inform the Thruway Authority staff about disruptions. Connections with law enforcement, first responders and tow truck operators will help minimize impacts from lane closures and accidents. Connections with the Thruway’s larger traffic management network will help synchronize operations, maintenance and repairs.

More than 85 of the 192 stay cables, ranging from 190 to 623 feet long, that will support the main span roadways were anchored the towers and tensioned to outside sections of structural steel the crews. That’s more than 700 miles’ worth of steel reaching from Tarrytown to Cincinnati.

I’d like to know what you think.
