Those driving near Adams Avenue and Harbor Boulevard in Costa Mesa, take note: There's going to be traffic.

City Hall is nearing completion on its $3-million project involving replacing medians and other improvements for the busy intersection. Officials said Friday that the work is about 70% done, and traffic delays are expected for the next two weeks.

A "significant impact" is expected in the mornings along Adams' eastbound direction. During the evenings, expect traffic in the westbound side, officials said.

Signs will be posted and the traffic signals will also be adjusted during this period, according to a city news release.

Residents seeking additional information are asked to call (714) 754-5017.
