Cost Estimates and Funding
November 2009 Capital Cost Estimate:
$2.6 - $3.6 billion (year of expenditure dollars)
The cost estimates are for construction of a replacement bridge with light rail to Clark College and
interchange and pedestrian/bicycle improvements on five miles of I-5. This cost estimate includes the proposed
savings that would results from several design refinements that will be considered by the
Project Sponsors Council Dec. 4, 2009.
Estimates are based on year of
expenditure dollars, or the projected year the money would be spent. The
estimate assumes that construction could begin in 2012 and last five to
seven years. The cost range does not include operating and maintenance
costs.
The ultimate cost and time to complete a project is subject to many variables,
including inflation, demand for materials or labor and the availability of funding. The
range is determined through a risk-based analysis that estimates the probability that
actual construction costs will fall somewhere within the range. More information
on cost estimation may be found on the WSDOT
Web page on the
Cost Estimate Validation Process.
