Potential Night Work

Please note where repair segments may require night work. Portland's Noise Office granted the Piedmont project a noise variance permit for work on or near N Lombard Street. If high traffic volume or other circumstances prevent work from occurring during normal daytime construction hours, the noise variance permit will allow the contractor to complete work between 8:00 p.m. and 6:00 a.m.
