Notice from Alaskan Way Viaduct and Seawall Replacement Program
Dear Neighbor:
Drilling crews working for the Washington State Department of Transportation are continuing to study the soil underneath city streets in preparation for replacing the central section of the Alaskan Way Viaduct. We are examining an alternative for this replacement that would move SR 99 into a bored tunnel beneath downtown.
During the week of January 4, crews plan to drill test holes at several locations in the Belltown neighborhood to locate utilities. After drilling the test holes, crews will begin more extensive drilling to obtain soil samples at each location.
What you can expect
The drilling to locate utilities will take approximately one business day. Crews will use a concrete saw to create a small hole at the following locations:
In the sidewalk on Third Avenue south of Bell Street.
In the parking lane on Fifth Avenue north of Battery Street.
In the parking lane or sidewalk on Fifth Avenue north of Wall Street.
Crews will return later in the week to begin more extensive drillings at these locations. They will excavate a hole approximately 170 feet deep and block off a work zone of 120 feet at each site. During drilling in the parking lanes, several parking spaces will be unavailable adjacent to the work zone around the clock. If crews must drill in the sidewalk, they will attempt to maintain a pedestrian walkway around the work zone. When drilling is complete, crews will restore and reopen the parking lane and sidewalk.
Construction schedule and noise
Work will typically occur from 8 a.m. to 5 p.m., Monday through Friday, and is expected to last approximately 5 to 15 business days. Work hours may include weekends if necessary to complete the soil sampling on time. This work will produce vibrations and noise but will not exceed the limits established by the City of Seattle noise ordinance for daytime outside construction activities.

Sincerely,
