Nighttime work this week
For the week of Nov. 23, nighttime work includes: removal of the excavator from the Benson Road Bridge area on I-405 and bringing in cranes in the median to work on a reconstruced Benson Road bridge over I-405. Crews will also be sawing and sealing joints along I-405, weather dependent, between SR 167 and SR 169 and delivering rebar and moving concrete barriers.
What you may hear:
Heavy equipment noise such as truck and excavator engines and intermittent high pitch sawing noises.
New slopes are stable
Lately we’ve received a few questions about our new slopes near I-405 close to the Benson Road Bridge in the Renton Hills and Rolling Hills neighborhoods. Recent rains have caused part of the mulch and top soil to run down or slough on the hill. We want to reassure drivers and area residents the hill is in no danger of sliding. Our slopes are reinforced and engineered to be structurally sound. We’ve laid a solid foundation, supported by sandstone bedrock. We’ll maintain the existing stable soils through the construction phase and until Mother Nature takes hold. Our goal is to provide suitable conditions for new plants to grow.
Environmental bath tub keeps water clean
One measure we’ve used to prevent stormwater contamination is use of a giant "bath tub." The bath tub is a filtered pit filled with large rocks and multiple layers of filter fabric and a sand layer to remove sediment particles from the water. Once the water is clean, it can be released back into the environment.
We keep a sharp eye on our environmental footprint to protect the water quality of the Rolling Hills Creek and Cedar River. We’re controlling stormwater runoff by minimizing the disturbed area, stabilizing slopes as they are constructed, and diverting clean water away from work areas. We store and clean the construction stormwater on site. During the recent heavy downpours, we used the best practices available to keep water clean.
What’s next?
We’ll finish preparing the slopes to support native trees and shrubs - similar to the roadside character and natural environment elsewhere along the I-405 corridor. The plants will develop into a productive, naturally-functioning, self-maintaining ecosystem over the life of the project and beyond. We plan to plant thousands of trees and shrubs this fall and winter when plants have the best chance to thrive.
