A construction crane has moved in on Fourth Avenue at the site of a future apartment complex that is on the rise.

Developers of The Union on Sixth got more than $36 million in permits for the project, starting in the 300 block of East Sixth Street.

It will have around 250 apartments in a mix of sizes, along with ground-floor retail.

Developers worked with an alliance of area businesses to work out concessions that would minimize the impact on Fourth Avenue and the surrounding neighborhood.

The complex is expected to open next year.
