• To minimize traffic impacts on Coast Highway, some activities may need to occur outside normal working hours.

Specific to Coast Highway and Dover Drive at Location #2:

• K-rail is installed, temporarily closing the bus stop turnout. OCTA Stop 4933, Routes 1 & 55, are closed until further notice. Use the prior or next bus stop. Visit OCTA for more information.
• Crossing path under Coast Highway is closed. Please take the appropriate detours.
• Sound panels are installed by the nearest neighbors to mitigate noise.

• We are working closely with the City of Newport Beach and Caltrans to minimize impacts and appreciate the community’s patience as we perform this work. The safety of the public and our crews remain our top priority.
