I-90 Front Street Overpass repair
What happened?
On the morning of March 14,
2015, an over-height dump truck
punched a hole in the I-90
overpass over Front Street in
Issaquah.
Upcoming repair work
The repair project will be
advertised for bidding on
Sept. 15, with construction starting
in Jan. 2016.
Repair work will happen at night.
The right shoulder of eastbound I-
90 on the overpass will remain
closed to traffic until repairs are
complete.
Significant damage
WSDOT bridge engineers
inspected the damage and found
that the hole was in one of the
structure’s girders.
While deemed safe for traffic, the
girder will need to be replaced.
