For the next four months, the on-ramp at Euclid Street to the northbound Santa Ana Freeway will be closed to motorists as freeway construction work continues.
The closure will allow for construction of a new on-ramp, to increase freeway access and to provide better traffic flow on local streets.
Anaheim officials have long awaited the ramp improvements to ease the way to the Anaheim Plaza shopping center.
During the closure, motorists traveling north on Euclid can turn right at Crescent Avenue and right again onto Loara Street to get to the northbound freeway.
In other freeway improvements, workers early this morning were expected to place steel structures to support a new bridge at Harbor Boulevard.
The Harbor freeway overpass is the only steel structure on the 9.5-mile stretch of the $1.1-billion freeway improvement project through North County.
The four steel structures are each 200 feet long and weigh 220,000 pounds.
The new bridge will be slightly wider to make way for a pedestrian walkway.
