The city council wants to create closer links between Argyle Street and nearby Buchanan Street with new lighting, streetscape improvements and a new market area.
The Council will redesign new street lighting and replace all existing street furniture including benches and bins to tie in with market "pods" and outdoor café's areas..
"New illumination will help create a safer atmosphere that has traditionally eluded that area of the city centre after dark," said the local authority.
"Designers will also be asked to look at the possibility of greening certain areas using vertical gardens."
Council leader Gordon Matheson, said: "Argyle Street has sometimes been seen as a poor relation to Buchanan Street in street design and buildings."
National Association of British Market Authorities recently completed a feasibility study and detailed design work was several months away, said Glasgow.
