Federal Aid Capital Maintenance

General Description:

Construction includes replacing asphalt pavement and improving adjacent pedestrian ramps as needed. Some areas have been identified as needing a slightly more extensive amount of maintenance repair. Asphalt in these areas will be removed, then a portion of the base material will be removed and replaced, followed by the placement of new asphalt pavement. The following street segments will be included in this project:

Curtis Road, I-184 south off-ramp to Morris Hill Road, work began on October 1st. Crews will remove the existing asphalt, re-grade the surface, and then repave the road. To accommodate this work, the road has been restricted to one lane in each direction. Work will be done on one side of the road at a time so that vehicles will always be traveling on pavement. Lane restrictions will remain in place until October 8th, weather dependent.

From October 9th-14th, crews will continue to pave the top layer of asphalt. Four lanes will be open during the morning and evening rush hours (6:00 a.m. to 8:30 a.m. and 4:30 p.m. to 6:00 p.m.). Daytime lane closures between 8:30 a.m. to 4:30 p.m. will be used to finish the remaining portion of work.

This work will cause travel delays, ACHD encourages commuters to consider alternative routes as appropriate.

Why do it this way? This method avoids the confusion of having the entire road as a gravel surface. When there is a gravel surface, crews cannot temporary stripe to delineate the travel lanes. Given the fact that Curtis is a five-lane road, it was determined that having the entire surface as gravel would not be as safe or as effective. This method also has the added benefit of greatly reducing the time of the overall duration of construction--one week as opposed to three or four.
