4th Ave S near I-90 is a very active corridor for pedestrians, freight, buses, and general-purpose traffic. The site is bounded by T-Mobile Park directly southwest and the Chinatown/International District directly northeast. Downtown Seattle is approximately 1/3 mile north. Large numbers of pedestrians use the sidewalks in these areas, often traveling to Mariners games after shopping and dining in Chinatown or exiting a bus downtown. However, unfamiliar walkers encounter a surprising sidewalk gap near S Royal Brougham Way. They often find themselves walking in the street, picking their way through puddles and brambles, or darting across the 7-lane road unexpectedly. In the Citys 2016 Pedestrian Master Plan, this sidewalk gap ranked highly on all metrics safety (expected crash reduction), equity (serving the most vulnerable populations), and health (the projects ability to improve mode shift, including access to nearby public transit). Ongoing public outreach has confirmed the need.

Project Description
This project construct a concrete sidewalk to provide a seamless walkway between downtown, the stadium district, and numerous bus stops along the corridor. The new sidewalk on the west side of 4th Ave S will also lead directly to and from the King Street Station overpass providing access to regional transit services and intercity passenger rail. The new sidewalk will be designed to carry unusually high volumes, varying from 7 feet on typical sections to 10.5 feet near intersections. The project scope will include other pedestrian safety upgrades at intersections, including curb ramps and pedestrian push buttons on the sidewalk as well as crosswalks and stop bars within the intersections.
