In April 2013, Caltrans will commence a repaving project that will include all 210 Freeway on and off ramps in La Cañada Flintridge. The project will consist of grinding down the asphalt on all ramps and resurfacing with rubberized asphalt. All construction work will be done at night with ramps open for use during the AM and PM peak hours. Consecutive ramps will not be closed for construction in order to minimize the impact of detours. Construction on individual ramps is expected to be completed within a 24 hour period. Warmer weather conditions are required for this construction, therefore, the project cannot begin until the spring.
