WI 794 - Lake Parkway:
WI 794 serves as a southern extension of I-794 on the south side of Milwaukee. The highway was built as an expressway because, while the local people wanted a new highway in the corridor, they were opposed to a high-speed freeway. In addition, build WI 794 as an expressway saved a lot of money. There is only one traffic light on the expressway, and the low speed limit of 40 or 45 mph seems unwarrented. Yet if the speed limit wasn’t this low, the highway might not have been built due to resident opposition. One substandard feature along the expressway is that there is no left-hand inside shoulder. Giving some credit to being called a parkway, the median is made of decorative bricks and curbing.

Junction Log:
The one traffic light on the expressway is at the Oklahoma Ave ramps. Including an interchange here would’ve cost a lot since WI 794 was built next to an active rail line in this area. This signal also serves to make the residents happy by slowing down traffic.
