Crews will begin repaving Bellevue's most beat-up streets this week. With regular maintenance, the city keeps streets in safe condition and only has to replace the top layer of asphalt in its annual "overlay" program.
The overlay program, focused this year on the city's midsection, between Interstate 90 and Bel-Red Road, begins today and will continue through October. Over those six months, 27.5 lane miles of residential roadway and one mile of arterial streets are scheduled for repaving at 82 different locations.
Since the overlay program began in 1991, more than 550 lane miles of roadway have been repaved.
This year, the first projects start west of Bellevue Way and generally workers will move in a clockwise direction, repaving streets in the Wilburton, Overlake, Lake Hills, Eastgate and Woodridge neighborhoods. Overlay Map
Next year, the overlay program will address needs south of I-90. Last year work took place in the city’s north end. Projects are concentrated in geographic areas to reduce costs.
During an overlay operation, old asphalt is planed down so the new overlay will match the concrete curb and gutter. A week or so later, a paving machine lays down two inches of new asphalt, followed by a heavy roller that presses the asphalt into place. Informational signs and "No Parking" signs will be used to inform residents about repaving work.
If a roadway is neglected for too long, all of the old asphalt must be removed, then replaced by about eight inches of new asphalt. This complete rebuild can cost up to three times as much as an overlay.
The contract for this year's repaving work, awarded to Lakeside Industries, is for $2.92 million. In coordination with this year's overlay program, the city also will construct 79 curb ramps at a cost of $511,000 as part of an ongoing effort to comply with requirements of the federal Americans with Disabilities Act. Last year, a record 211 new ramps were installed.
