SDOT is underway with construction of pedestrian safety improvements on 12th Avenue at the intersections of East Howell and East Olive streets. This work will require the temporary closures of East Howell and East Olive streets to all traffic at 12th Avenue so that crews can safely and efficiently demolish and build new sidewalk, curbs, and curb ramps.
Crews have already been working on the west side of 12th Avenue at East Howell and East Olive streets and restrictions are currently in effect on the west side of these intersections. Through-traffic restrictions are expected be in effect beginning Thursday, October 15th on the east side of the intersections so that crews can begin working on the east side of 12th Avenue. Residents, businesses, and travelers in the area should expect these closures to last for the duration of construction, anticipated to complete in early November. The project team will work to restore access at this location sooner if at all possible.
Bike lanes on 12th Avenue between East Pine Street and East Denny Way will also be closed and people riding bikes will need to merge with vehicle traffic. Pedestrians will be required to use the east side of 12th Avenue and pedestrian pathways will be clearly marked.
During construction you can expect:
- Construction activity from 7 a.m. – 5 p.m., Monday – Friday.
- Parking and lane restrictions on 12th Avenue between East Pine Street and East Denny Way. A flagger will be present to maintain two-way traffic.
- Temporary closures on E Howell and E Olive streets at 12th Avenue. Local access will be maintained at all times.
- Pedestrian and bicycle detours around the work areas.
- Temporary closure of the United States Postal Service collection box at the corner of 12thAvenue and East Howell Street.
- Noise, dust and vibration associated with concrete removal and paving.
The goal of these improvements is to allow safer crossings for pedestrians and improve mobility for all users. Curb bulbs help reduce crossing lengths and improve visibility between people walking and people driving. The work will include:
- Curb extensions to facilitate safer, shorter crossings for people crossing the street
- ADA-compliant curb ramps for smoother and better access
- New striped crosswalks that cross 12th Avenue at both intersections
- Drainage improvements at both intersections
SDOT appreciates the public’s patience while this work is being completed. This project is funded by the Bridging the Gap transportation levy, through the Neighborhood Street Fund Program.
