May Creek Bridge closes from June 21 until August

June 15, 2010

The bridge near the intersection of Southeast May Valley Road and state Route 900 will close June 21 and remain closed for most of the summer, as workers dismantle the aging structure and build a replacement bridge.

King County plans a modern May Creek Bridge to replace the timber-supported, 60-year-old span across the north fork of May Creek. Crews posted signs near the bridge last week to alert drivers to the shutdown and construction. Detour signs will be posted for the duration of the closure.

The replacement bridge will be longer, with wider lanes and shoulders. Moreover, the $1.7 million project has been designed to bear heavier loads.

The narrow roadway on the existing bridge constricts traffic at the nearby intersection of state Route 900 and Southeast May Valley Road.

King County Road Services Division planners started readying for the project several years ago. The agency contacted the state Department of Transportation, emergency-service providers and the Issaquah School District to prepare.

Sara Niegowski, district spokeswoman, said the timing dovetails with summer break. The school year ends June 17 and starts Aug. 31.

Watch bridge rebuild and traffic with online camera

April 20, 2009

NEW — 6 a.m. April 20, 2009

The King County Road Services Division has a new traffic camera in the May Valley area to help people keep tabs on construction of the new Bandaret Bridge and related traffic disruptions.

The existing Bandaret Bridge spans upper Issaquah Creek on Southeast May Valley Road between 230th Avenue Southeast and 231st Place Southeast. Construction is being done in stages to minimize the impact to the traffic by avoiding a full closure of the bridge.

During construction, the two lanes of two-way traffic at the bridge have been routed to a single lane and controlled by temporary traffic signals and/or flaggers. These restrictions are in place 24/7 through November.

 

The first of 10 pilings is lowered into its hole for the new Bandaret Bridge over Issaquah Creek on Southeast May Valley Road. The 63-foot long ‘cage’ of rebar, weighing 17,000 pounds, was lowered into an 80-foot deep hole, with the cement pour to follow. Traffic is alternately one lane until November, when the $5.5 million bridge is finished. — By Greg Farrar

Southeast May Valley Road restricted to one lane until November

March 19, 2009

NEW — 9 a.m. March 19, 2009

Traffic on Southeast May Valley Road is restricted to one lane just west of Issaquah-Hobart Road. The closure started at 6 a.m. today.

Crews are replacing the Bandaret Bridge across Issaquah Creek. The roadway is expected to be narrowed to one lane over the creek through November.

A new temporary traffic signal at 230th Avenue Southeast and May Valley Road will allow vehicles to proceed through the construction zone in one direction at a time.

The King County Department of Transportation is overseeing the $5.5 million project.

The existing bridge, near Issaquah-Hobart Road between 230th Avenue Southeast and 231st Place Southeast, carries about 5,100 vehicles daily – too many for an aging, deteriorating structure, transportation officials said.
