The minimum width for temporary traffic control lanes on a street with a 35 MPH speed limit is typically determined by safety regulations and guidelines, which prioritize vehicle movement and safety of all road users. A width of 10 feet is generally accepted as adequate because it allows for the safe passage of vehicles without compromising the ability to navigate comfortably within the lane.
At a speed limit of 35 MPH, accommodating larger vehicles and providing an adequate buffer for spontaneous maneuvers is essential. As such, 10 feet offers a balance between enough space for both standard vehicles and larger ones, ensuring that lanes are safe for all while also being practical for traffic control setups.
The other widths provided, either narrower or significantly wider, may not align with the standard practices for this speed limit, where 10 feet serves to facilitate proper control without excessive space that could lead to inefficiencies or challenges in managing traffic flow.
