Flooding that occurred in spring 2011 and several
other days of work stoppage due to inclement weather and high river levels
have led to a revised construction schedule for the Milton-Madison Bridge
Now the opening of the new bridge truss in its temporary position is scheduled
to take place in late April. That will be followed by demolition and removal
of the old bridge truss from May to July. Then the new truss will be slid
into its permanent position atop the rehabilitated existing concrete piers
in late July, according to Bridge Construction Team officials.
Walsh Construction Co. lost 108 days in 2011 due to the large amount of
rainfall that occurred in the spring of that year. What is normally 35
inches of rain falling in this area of the Ohio River Valley each year,
in 2011 it reached a high of 70 inches, officials said. So far this year
several days of work stoppage has occurred due to high river levels and
the sub-zero temperatures, which have prevented workers from pouring concrete
on the new bridge truss deck.

last steel section of the new Milton-Madison Bridge truss is set
into place in December. Work on the bridge deck was stalled in January
due to high river levels and sub-zero temperatures. It is hoped
that traffic can be diverted onto the new truss in late April and
that it can be slid into its permanent position in late July. The
new targeted completion date for the project has been moved to Oct.
As soon as the temperatures return to normal, workers will set to work
completing the bridge deck and connecting ramps to the truss in its temporary
position just 15 feet downstream from the old bridge. Traffic is expected
to be routed onto the new bridge truss in late April using the original
approaches, which have been widened and rebuilt on both sides of the river.
Traffic will enter on the permanent approaches, then take a short dogleg
onto the new bridge truss while it is in this position. The temporary
supports and dogleg approaches will be removed after the new bridge truss
is slid into its permanent position.
When complete, this will be the longest bridge span slid into place in
this manner, topping a recent 12-hour sliding of the Sellwood Bridge that
took place Jan. 19 near Portland, Ore. That bridge span of 1,100 feet
was being hailed as the longest such bridge slide in the nation. It involved
moving the 87-year-old Sellwood Bridge into a temporary position so a
new bridge can be built in its place.
New bridge truss opens to traffic in its temporary position
May-July: Demolition and disposal of old bridge truss
Late July: New bridge truss to be slid atop rehabilitated
Oct. 14: Project to be complete
The planned Milton-Madison Bridge slide, meanwhile, involves moving a
2,427-foot new truss into its final resting place. Using hydraulic jacks,
the slide is expected to take several hours during the second of two planned
five-day closures. The event also is expected to draw a large crowd, both
from the public and the engineering community.
The current weight limit of three tons is expected to be raised to 15
tons on the new truss in its temporary position. Therefore, semi-trucks
will still be prohibited from crossing the bridge until it is slid into
its permanent position.
The new completion date for the project has been moved to Oct. 14, meaning
Walsh Construction Co. equipment must be out of the main footprint
of the bridge by then and the park shelter and volleyball court must be
replaced on the Madison side. The Jay-C Park will be rebuilt later in
an agreement with the city, officials said. Even after the Oct. 14 completion
deadline, Walsh can move its equipment to a staging area it created on
the Milton riverfront on land it is leasing from Kenny McCoy.

Construction Co. and the Kentucky Department of Fish and Wildlife
in mid-January mounted a newly built falcon nesting box on the new
bridge truss. They are hoping the birds adopt the nesting box when
they return this spring.
Meantime, a committee of Madison and Milton citizens are planning a free
community-wide party on July 27 to celebrate the bridge sliding event.
Named the Bridge Party...Celebrate the Slide, the event is
scheduled from 5-11 p.m. on the Madison riverfront. It will feature live
music, food booths and childrens activities. Madison singer-songwriter
Rusty Bladen is writing a song for the occasion and has been asked to
perform it at the party. The movie Cars will be shown on a
large screen beginning at dusk.
As for the falcons who return each spring to nest under the bridge, officials
from the Kentucky Department of Fish and Wildlife have constructed a new
nesting box. Together with Walsh Construction officials, in mid-January
they placed the new box under the new bridge truss near the Milton side.
They are hoping the falcons will accept the new nesting box, but without
a deck in place yet to cover the box, officials worry the birds may not
move in. The falcons like the cover the deck provides and have made a
home under the old bridge for many years.
While it is uncertain whether the falcons will like and adopt the new
Milton-Madison Bridge, one thing is certain: local residents and commuters
will love having a new, wider, safe bridge to cross.
