Design Construction Impacts
This project overlaps proposed improvements included in the Nickel project entitled "SR 9-212th Street SE to 176th St SE - Stage 3". Under the present scope, the left turn lanes at 188th St. SE is within the scope of the widening work of another project, SR 9 212th St. SE to 176th St. SE - Stage 3. That project is scheduled for construction three years after this project. This means that any improvements made at 188th Street SE in this project will become obsolete within a few years.
The recent Engineer's Estimate significantly exceeds the project budget. The cost increase is due to increased wetland mitigation, stormwater treatment/detention, and soils issues related to widening the roadway in a floodplain. We are in the process of refining the design to identify cost saving opportunities.
