fter
years of controversy, the pedestrian bridge over the Missouri
River is in the midst of becoming reality. Construction on the $22
million bridge began in October of last year with an
estimated
completion date of November 2008.

Construction crews began
installing the first of two pylons last week that will support the
bridge. Each pylon - or tower - will be 204-foot high and will be topped
with a 25-foot steel tip. Over 40 cables will be dropped from the
top of each pylon and be connected to the bridge deck. Observers
can view a 299-foot trestle that extends out over the river on the
Iowa side. This is a temporary structure built to support the
large cranes that are needed to dig a hole in the bedrock
below.

Preparation is done in front of the Riverfront Place condominiums
in Nebraska. The sign indicates the riverfront trail is closed for bridge construction. |

Once completed the 2,700-foot bridge with a 506-foot span across the
river will connect nearly 150 miles of trails in Nebraska and
Iowa. When illuminated at night, the bridge's twin spires and
cable stays will light up the Missouri River for miles.Entrance
to the bridge on the Omaha side will be located between the
Riverfront Place condominiums and the National Park Service
regional headquarters. The Council Bluffs entrance will be just
north of Playland Park. A proposal to develop this area
was recently submitted to city leaders. The vision includes a plaza
that will welcome visitors
coming across the bridge and a three-acre park just to the east.In
Council Bluffs, work is also continuing on a aquatic habitat. An
old river chute northwest of I-29 and Avenue G is being cleared to
benefit fish and wildlife. The restored chute will have a depth of
around 5 feet during normal summer river flows and will be 300
feet wide from bank to bank. The chute, which will empty back into
the river west of Avenue G, is about a half-mile north of the Iowa
pedestrian bridge entrance. The nature area surrounding the chute
will be incorporated into any park plans at the base of the
bridge. Boaters on the river will need to pay special attention
this summer when they navigate close to the bridge construction
site. Buoys or other restriction signs may be placed in this area
as work continues.
