During Frank Zeidler's administration, Milwaukee grew industrially and never had to borrow money to repay loans. During this period, Milwaukee nearly doubled its size with an aggressive campaign of municipal annexations: large parts of the Town of Lake and most of the Town of Granville were annexed to the city. The park system was upgraded. Zeidler spearheaded planning and construction of the beginning of Milwaukee's freeway system, and turned it over to Milwaukee County in 1954. A transportation advocate claims that Zeidler always maintained that the projected Milwaukee freeway system should have been built and that the city's competitiveness had been compromised by the failure to complete the planned system.
