TAHOE-TRUCKEE, Calif. — This construction season will be a busy one. Thirteen major roadway projects around Lake Tahoe are planned this summer. While construction season within the basin is typically between May 1 and Oct. 15, one or more projects may start next month, weather permitting.

“ … We understand the inconvenience of traffic delays, but we ask for motorists to be patient as we continue to make progress on these important projects that are helping to protect Lake Tahoe and improve highway safety,” said Steve Nelson, Caltrans District 3 public information officer, adding that it will “be the busiest season of construction in the Tahoe Basin” in several years.
