Design Construction Impacts
The construction of this project has been advanced by a year utilizing a design-build procurement method. Construction is anticipated to begin in mid-October 2008 and be substantially complete before June 30th, 2011. The escalating cost of steel girders and rising fuel costs have impacted this project cost estimate by 10%.

Impacts to Traffic
The Construction schedule is compressed and the work is sequenced to minimize traffic and pedestrian impacts as well as major events at the adjacent facilities. Traffic will be mitigated by first constructing the 1st and Atlantic intersection improvements followed by the I-90 Atlantic ramp and the Royal Brougham Way grade separation.
