Dexter Avenue N - Fremont Avenue N (Fourth Avenue N) to Roy Street

Project Update:  September 27, 2011

Street improvements will benefit all Dexter Avenue North users for many years to come

In March 2011, the Seattle Department of Transportation (SDOT) began work to improve Dexter Avenue North between Fourth Avenue North and Roy Street.

We are pleased to announce this work has been completed on schedule and on budget.

The Dexter Avenue North Project includes:

1.5 miles of new pavement between Fourth Ave N and Roy St

New sidewalks in areas that were in poor condition

20 new pedestrian ramps

Two new crosswalks on Dexter Ave N

Buffered bike lane on each side of Dexter Ave N

Dedicated transit islands at 10 of 12 bus stops

New storm drains, surface water detention facilities and a subsurface drain system on the west side of Dexter, just south of 4th Avenue N

Green bioretention surface water overflow area near Crockett St

The Dexter Avenue North Paving Project was funded by the Bridging the Gap (BTG) Transportation Levy passed by Seattle voters in 2006.  BTG funding has enabled SDOT to make critical transportation improvements in every Seattle neighborhood.

Many thanks for working with us during construction. Your patience and cooperation while we completed the necessary work was truly appreciated.

We hope you enjoy your new street!
