Under the Alberta electoral boundary re-distribution of 2004, 13 Street forms most of the dividing line between Lethbridge-East and Lethbridge West.

The first representative returned in the election held that year was Social Credit candidate Richard Gruenwald who won the district with well over half of the popular vote.

Gruenwald would run for a second term in the 1975 election and would be defeated finishing a distant second place behind Progressive Conservative candidate John Gogo who took almost 60% of the popular vote.

After the election he was appointed to the provincial cabinet by Premier Ralph Klein as Minister of Advanced Education and Career Development.

The fourth representative returned from the riding was Progressive Conservative candidate Greg Weadick who won his first term as MLA in 2008, and was re-elected in 2012, but was defeated in the 2015 general election by Shannon Phillips of the NDP.

In 2019, Phillips held onto the riding with a reduced margin of victory over the second-place finishing UCP candidate with just 45% of the popular vote.
