Undercrossing construction hindered by wet weather
June 8, 2010
Rain has slowed construction on the Interstate 90 Undercrossing and, because soil at the site is sensitive to moisture, crews must take care to manage storm water runoff and prevent soil erosion.
During Memorial Day weekend, the city monitored storm water runoff from the site. The results showed low levels of turbidity, or murkiness from soil and other particles — well below the threshold required for corrective action by city code. Runoff turbidity levels remained low last week.
Construction workers broke ground on the undercrossing in early May. Initial plans called for the road link to be completed by early fall.
Crews will build a two-lane roadway from the traffic signal at the post office along Northwest Gilman Boulevard and link the road to the rail corridor behind Gilman Station. The road will form a T-shaped intersection at Southeast 62nd Street, continue along 221st Place Southeast and end at Southeast 56th Street, across from the East Lake Center retail complex.
