Preliminary Design is the stage of a proposed project's life where plans and engineering are developed to a level where the communities and public agencies can agree to advance the project to final design and construction. The original Preliminary Design for the Route 7 Wittpenn Bridge project was completed in November 2005. After the completion of the original Preliminary Design, the project underwent a Value Engineering Rightsizing Review. To account for this review, a revised Preliminary Design was completed in August 2007.

The following are some of the activities that were undertaken during Preliminary Design:

• Preliminary roadway design
• Preliminary structural design
• Complete Right of Way plan
• Prepare drainage design
• Prepare lighting design
• Prepare environmental permit applications
• Gather subsurface information
• Complete geotechnical foundation design
• Complete geotechnical roadway design
• Community relations
• Conduct environmental testing
• Mitigate cultural resources
• Prepare traffic signing, striping and signal plans
• Prepare ITS facilities design
• Prepare PAECE reports
• Subsurface utility engineering testing
• Prepare preliminary construction cost estimate and schedule
• Prepare traffic staging plans
• Review constructability
