Utility Work to Impact John Street and Pontius Avenue N
Crews have closed John Street to thru traffic between Minor Avenue N and Yale Avenue N to install
duct bank and to perform other utility work for the Denny Substation. The closure is scheduled to be in place around the clock for up to four months.
The John Street and Pontius Avenue N intersection will also be closed for up to two months.
- Planned word dates: December through early April
- Work hours: 7 a.m. to 5 p.m. Monday through Friday, with the possibility of some Saturday work.
The closures will be in place 24 hours a day, seven days a week.
- Road closures: No thru traffic on John Street between Minor Avenue N and Yale Avenue N;
John Street and Pontius Avenue N intersection will be closed
- Pedestrian closures: Because the crosswalk across Pontius Avenue N at John Street is closed,
a mid-block crossing of Pontius has been provided.
The sidewalk on the south side of John Street between Minor Avenue N and Yale Avenue N is also closed.
The Denny Network Project reached a key milestone in the third quarter of 2017 with the installation of the last of 30 underground vaults.

- Republican Street between 9th Avenue N and Terry Avenue N
- Republican Street and Pontius Avenue N intersection

- Harrison Street between 9th Avenue N and Boren Avenue N
- Thomas Street between Pontius Avenue N and Minor Avenue N
- Thomas Street and Boren Avenue N intersection

Crews have also begun work on street improvements along Thomas Street between Pontius Avenue N and Minor Avenue N,
which includes a festival-style street design, new street and pedestrian lighting, water permeable sidewalks,
and additional trees and landscaping.
