The following are crude notes and links I have gathered during my research. The information may be in various languages and is being updated during the research process until a full article is written.
COST OF I-30 CALATRAVA BRIDGES BROKEN DOWN:
$798 million – Total cost of the Horseshoe project to reconstruct the Interstate 30 and Interstate 35 bridges over the Trinity River, including the Santiago Calatrava-designed bicycle and pedestrian bridges alongside I-30.
$114.9 million – Cost of the Santiago Calatrava-designed bicycle and pedestrian bridges ($102.9 million) and frontage roads ($12 million).
$74 million – Original planned cost for construction of Calatrava bridges.
$91.3 million – Federal funds available to cover cost of Calatrava bridges and frontage roads.
$11.6 million – Regional Transportation Council Funds for Calatrava Bridges and frontage roads
$12 million – Funding gap expected to be covered through $5 million Trinity Trust Foundation gift, money from city’s public arts fund and through cost-cutting
Issue: the state of Texas wants the three bridges for their functionality and to replace old decaying roads. The city of Dallas has its mind set on signature bridges to give this part of the town a different look. The city however does not have the money for this.
The Margaret McDermott Bridge, the second signature bridge, was originally scheduled to begin construction in 2011 with a completion date of 2014. However, as of December 2011, this bridge is now funded within the Project Pegasus initiative with construction contracts to be awarded in mid-2012; the new plan will feature ‘toned-down’ elements of its original arch design. Calatrava is still scheduled to perform design work.
city of dallas to decide on mcdermott bridge: does it want the 114 million version of a 74 million version that is less fancy but has the same functionality. the original plan by calatrava was even more expensive, including motorized traffic as well as pedestrians and cyclists. the current plan has been reduced to only pedestrians and cyclists.
The current $114 million I-30 plan was reduced to just hike and bike bridges along side a standard state roadway because the original Calatrava design was far more than the city could afford.
Griggs said the scaled down plan is still around $40 million more than it was to have been.
“The cost overruns this early in the process are outrageous. These bridges can be very expensive when they’re designed by Santiago Calatrava and we don’t want these to be blank check,” Griggs said.
the city council decided to go through with the 144 million usd version of the project:
The rest of the City Council voted in favor of a plan to close the $12 million gap by accepting a $5 million contribution from the Trinity Trust, transferring several million from other city bond funds and seeking “value engineering” savings from Calatrava and the contractor.
– the city council in its decision actually counts on calatrava to reduce costs. That would be a first in Calatrava history
Bridges look identical to Reggio Emilia bridges in Italy
