Final answer:
The question seeks a non-viable engineering solution to increased traffic on a previously quiet two-lane highway, where all provided options could potentially be viable solutions for traffic management.
Step-by-step explanation:
The question is about finding NOT a viable engineering solution to the traffic problems on a two-lane highway that has become busier over time. A viable engineering solution could be to create more turn only lanes, create more divided highways, design an interstate system through the area, or redesign bad intersections with stoplights. These solutions are intended to alleviate traffic congestion, improve safety, and manage the increased flow of traffic due to local population growth and development. However, the student's question asks for an option that is NOT a viable solution, which is not straightforward as all options presented could potentially address the traffic issues depending on the specific circumstances.
