Secretary
of Transportation Nathan Hayward could not have been clearer on
Jan. 2 when he declared at a press briefing: "We think it is
time to reach consensus and make something happen."
That
something will be a new four-lane bridge supported either by
concrete girders or arches straddling the Brandywine on five
piers at the location and elevation of the present structure. In
all likelihood, there will be a separate bridge for use by
pedestrians and bicyclists at the base of the piers.
The new bridge, to be sure, is
presently described as the third and fourth of four options that
will be officially presented for public comment at a
'workshop'-style meeting between 4 and 8 p.m. on Jan. 6 in

Arsht Hall
on the University of Delaware's Wilmington campus. The two other
options call for a separate two-lane bridge next to the existing
one, either of matching steel-girder or more modern
concrete-girder construction.
Hayward said that the final decision
will be based largely on public preferences expressed at the
'workshop'. That format allows for attenders to submit written
comments and give them orally to Delaware Department of
Transportation representatives. There is no public discussion or
testimony at the session.
The press briefing and an earlier
private presentation to elected officials and newspaper
editorialists were part of an obvious DelDOT effort to make a
strong case for an updated plan. As far as could be determined,
initial reaction to the new plan is favorable.

Secretary of
Transportation Nathan Hayward makes a point at a press
briefing. |

Hayward made no effort during his
presentation at the press briefing to give the competing options
equal billing. He described the proposed stone structures as
"harmonious with their surroundings" and referred to the
original bridge, and by implication its possible clones, as
having "been built 50 years ago in record time and at the lowest
possible cost."
He told Delaforum that his personal
preference is for the stone bridge with the arches.

The designs were produced by
Tallahassee, Fla.-based Figg Engineering Group, which is
nationally recognized for having designed bridges in scenic
venues. It promotes itself as specializing in "providing bridges
as art." No details were provided about how and when the firm
was, as the DelDOT presentation booklet said, "added to [the]
project team."
Marc Coté, project manager,
acknowledged that the new designs came out of an environmental
and historic assessment process which ran concurrently with and
continued beyond deliberations of a 38-member advisory
committee. The former held at least 18 plenary sessions over a
period of 10 months between September, 2000, and July, 2001, and
came up with a recommendation to build a parallel span. Hayward
and Governor Ruth Ann Minner formally accepted that
recommendation in February, 2002.
Hayward referred briefly to that
decision by remarking, "We have come up with a better way of
doing it."
As late as September, 2002, DelDOT
consultant Robert Kramer told Delaforum that

Hayward and DelDOT apparently prefer would replace
the present Tyler McConnell Bridge (above) with a
new structure using one of the two conceptual design
options illustrated below. |

the findings
and recommendations of the review group would not take
precedence over those of the advisory panel. The panel's
deliberations were all done in public session; the review
group's meetings apparently have had no outside attenders. At
least six Delaforum requests to be advised of the time and
location of its meetings were not responded to in timely fashion
by DelDOT's public relations department.
Coté said
the new designs do not reflect any change in position about the
project on the part of DelDOT, but are the result of "weighing
the effects of a new two-lane or four-lane bridge on the
historical resources" of the area. He indicated that building a
new four-lane bridge with fewer supporting piers "would have
less [adverse] impact." In any case, he said, such a review is
required by the Federal Highway Administration as part of any
project the federal government will partly finance.
In his
remarks, Hayward said that the difficulty in determining the
best way to alleviate the bottleneck caused by the existing
two-lane bridge along state route 141, which elsewhere along its
entire length is four lanes wide, is blending in with the
natural and historic attributes of the Brandywine Valley. "We
have [economic] growth and transportation needs coming right up
against the need to preserve Delaware's past," he said.
He said
the Tyler McConnell crossing "is not just a bridge," but a
significant element in an area that has both historic attributes
-- particularly the original Du Pont black powder mills at
Hagley and present-day commercial significance with major Du
Pont and Astra Zeneca facilities nearby.
That was
not as widely recognized a concern in 1952 when the present
Tyler McConnell Bridge was built. He said that the overriding
factor then was accommodating a desire by the Du Pont Co. to
provide better access to its then expanding Experimental
Station. "Du Pont paid $250,000, just a little less than half
the [total] cost toward building it," Hayward said.
He
dismissed any suggestion that the existing bridge could be
considered historic in its own right. Although it was an early
example of the use of what are described in the business as
'hammerhead' piers, Hayward said, "There is nothing unique about
those piers; they were put there because they were cheap and
fast."
The
proposed stone bridges, he said, can be constructed within the
$40 million authorized for the Tyler McConnell project in
DelDOT's long-range capital budget. He said the 'effective
cost', when future maintenance and anticipated major renovations
are taken into consideration, is actually less for concrete
construction. He said the new bridge will "last for at least 100
years."
Carolann
Wicks, DelDOT's chief engineer, said a new bridge could be
designed and built in about three years. Although she and
Hayward both said there is no specific timetable at this point
for doing so, Wicks said the status of an agreement with the
advisory panel that no construction will start until semi-annual
traffic counts show an immediate need is uncertain.
Noting
that the present bridge "is dreadfully congested, mornings and
evenings," Hayward said that proceeding to build a replacement
span is a responsible step. "Nobody is saying it's the wrong
thing to do; we think that it is the better thing to do," he
said.
