There are only a few ways to get off the Sammamish Plateau, and the city is about to close one of them for the rest of the year.

Sammamish Senior Project engineer Sam Park said construction got underway in August as the contractor started widening the two-lane road. It just can’t handle the 24,000 vehicles a day that use it, and this was promised to Klahanie residents when the area was annexed.

“We’re widening the road from two lanes to four lanes, and we’re improving the intersections from signalized intersections to roundabouts,” Park said. “There are going to be three roundabouts, and we’re removing a sag in the roadway by building a bridge.”

It is that bridge work that is going to cause the closure of this route that connects the Sammamish Plateau to Highway 202 and I-90. The bridge is 400 feet long. Park said the plan is to close Issaquah-Fall City Road at the end of the month, though the closure date is still in flux. This closure will last eight months.

“Everyone is going to have to find their way around it,” Park said. “We’re going to have to wait and see approach as far as how traffic is impacted.”

The closure extends from 247th and Klahanie Boulevard, which is about a quarter of a mile. The entire project, widening included, extends about two miles. Park said the new bridge will be about 25 feet higher than the current roadway, which dips significantly to the creek bed at the bottom of the sag. It will be two lanes in each direction, with bike lanes and sidewalks on both sides.

Where Is The Housing Inventory AND What's Happening With Local Home Prices?

“We’re improving the intersections and the roadway capacity,” Park said. “Safety is going up. Pedestrian safety is improving.”

The project also includes a dedicated crosswalk in front of the nearby middle school.

The city hopes to have the road portion of this project completed by the end of the year. There will still work to do on the old road, over the creek. It will be removed, and the culvert will be replaced, improving fish habitat on the north fork of Issaquah Creek.

The culvert was blocked long ago by a family of beavers. This new bridge will prevent that from happening.

In most areas we find that the highest "Closed" sale price year over year are homes closed in April. That means the home is typically listed in March or even late February with a closing date in April. Just one month later can cost a seller 10's of thousands as increased inventory creates more selection, less urgency for buyers and resulting lower prices.
