Del Mar officials said Tuesday a bluff collapse that closed northbound Jimmy Durante Boulevard on April 21 should be repaired by the first week of June.
The City Council declared a local state of emergency this week as crews worked to build a 120-foot-long retaining wall to secure the cliff.
The collapse between Luzon Avenue and David Way buried more than 100 feet of sidewalk, bike and traffic lanes under up to five feet of soil.
Construction of the retaining wall has been complicated by overhead power lines, and San Diego Gas & Electric in planning to shut down power to the section on Thursday.
To reduce traffic congestion, Del Mar is allowing rush-hour drivers to proceed through stop signs on Camino del Mar at 22nd and 27th streets with personnel flagging traffic at the cross streets.
Flaggers will also be posted during the Memorial Day weekend and the first two days of the San Diego County Fair.
