DISCUSSION: OOn June 23, 1997, the City Council authorized the award of Newport Boulevard (SR55) /Pacific Coast Highway (SR1) "Arches" Interchange Improvements contract to Brutoco Engineering and Construction, Inc., of Fontana, California. The contract provided for a new grade separation bridge at Newport Boulevard and Pacific Coast Highway, widening of the Newport Channel bridge, street widening, ramp reconstruction, and interchange landscaping. Construction operations began in September 1997 and were substantially completed by the end of May 1999 when a formal dedication ceremony was conducted. The widening improvements at Newport Boulevard and Short Street were delayed until the Orange County Sanitation District's contractor, Advanco Constructors, removed the old Lido Sewage Pump Station in mid - September 1999. The contract has now been completed to the satisfaction of the Public Works Department and we recommend formal acceptance of the improvements by the City Council.
