Project Description

This project includes widening northbound 4th Ave SW to add a dedicated right-turn lane at SW 148th St, replacing the existing traffic signal at 4th Ave SW, and constructing a new traffic signal at 6th Ave SW. The new right-turn lane will provide the current and future capacity needs for 4th Ave SW approaching SW 148th St. The existing traffic signal at SW 148th St/4th Ave SW does not provide protected left-turns for any leg of the intersection and numerous right-angle accidents are a result. The north/south legs are operated with split phases, which reduces accidents but decreases operational efficiency. A new traffic signal will correct these existing deficiencies and will provide technological upgrades for pedestrian amenities. Curb access ramps will be reconstructed to meet ADA compliance. A new traffic signal at SW 148th St/6th Ave SW will replace the existing pedestrian signal crossing SW 148th St. Visibility of the pedestrian signal from 6th Ave SW is limited and all pedestrian crossing legs will be made safer with a standard traffic signal. Vehicular traffic will have improved safety with controlled movements and dedicated left-turning phases. The existing limited lighting on SW 148th St will be improved with new luminaires installed on pedestrian poles and all new traffic signal poles.
