DC's Woodward & Lothrup, a.k.a. "Woodies", added a 150,000 square foot store to the mall, which held its grand opening in March 1976. It was the chain's tenth mall-based branch.

A mid-1970s site plan shows additions built as part of the mall's first expansion. The aforementioned Woodward & Lothrop sits at the end of a new North Wing. Moreover, two multilevel parking garages have been built and Hecht's expanded. MONTGOMERY MALL now encompasses 1,003,000 leasable square feet. There are around ninety-eight stores and services under its roof.
