OLYMPIA -- Starting on Tuesday, a new detour will reroute traffic between downtown Olympia and the city's west side.
The detour will completely separate traffic for the Fourth and Fifth Avenue bridges. Westbound users of the Fifth Avenue bridge no longer will be able to merge with users of the temporary Fourth Avenue bridge to proceed up the hill on Harrison Avenue.
Instead, drivers will have to use west Fourth Avenue and Perry Street as the connection between Harrison Avenue and the Fifth Avenue bridge.
Directional signs will be posted along the route.
The detour will last between nine months and a year and will allow construction workers to complete demolition of the old Fourth Avenue bridge and build a retaining wall along a steep, waterfront slope northwest of the construction area.
"We know that this is quite a change, and it is going to be difficult at first," said bridge project manager Tom Frare. "We believe that traffic will still flow smoothly through the corridor."
What's changing
A bicycle lane that heads west along Fifth Avenue will end at the base of the Fourth Avenue hill. At that point, cyclists are urged to merge with automobile traffic or travel west on the roadway's sidewalk.
Partial roadblocks will be placed where Harrison intersects Plymouth, Rogers, Percival and Foote streets to prevent drivers headed down the hill from cutting across those streets to get on the Fifth Avenue bridge. The nearby predominantly residential blocks will be closed to through traffic.
Pedestrians headed north from the detour route toward Garfield Elementary School will have a little extra help navigating the new traffic pattern.
Two Garfield Elementary School crossing guards have been stationed at the intersection of Perry Street and Harrison Avenue each weekday morning and afternoon.
An additional pair of crossing guards will be stationed at the Fourth Avenue and Perry Street intersection during the detour.
"Because of the additional traffic, we wanted to make crossing safer for the students," said Garfield Principal Bruce Walton.
Effects on transit
The detour also will affect bus routes.
Intercity Transit's Route 45 operates Monday through Saturday along a route connecting the downtown transit center, Westfield Shoppingtown Capital mall and the Capital Medical Center.
Beginning on Monday, it will use Fourth Avenue instead of Fifth Avenue to reach Harrison Avenue. When heading east toward downtown, the bus will use Fourth Avenue and turn left on Columbia Street to reach the Olympia Transit Center.
The detour will eliminate three bus stops: Fifth Avenue at Sylvester Street, Fifth Avenue at Yashiro Street and Fifth Avenue at Simmons Street.
Riders will be able to catch Route 45 at replacement stops that include Fourth Avenue at Simmons Street and Fourth Avenue at Yashiro Street. Bus arrival times will not change.
Six IT routes serve the west side. Except for unexpected delays, all west-side routes will maintain their existing schedules during bridge construction, said IT spokeswoman Meg Kester.
Construction crews from the Hamilton Construction Co. of Springfield, Ore., began demolishing the 81-year-old Fourth Avenue bridge in November.
A new bridge, which will have three vehicle and two bicycle lanes, could be open for use by spring 2004.
The bridge will have sidewalks with semicircular viewpoints for pedestrians to use.
