HWC performed surveying services at the start of the project to help HWC’s transportation team better understand the scope of the project as they provided roadway design, utility coordination, traffic signal planning, and public information meeting coordination services for INDOT’s US 31 Road Diet project.
The need for this project is to address a number of rear-end traffic collisions while enhancing road safety and the overall quality of traffic flow. US 31 is a four-lane urban principal arterial. Currently, there are no designated lanes for both northbound and southbound vehicles turning left along US 31 in Scottsburg, which has led to this increase of rear-end traffic collisions.
The survey department provided route survey services, supplemented by aerial mapping. These deliverables aided in HWC’s collaboration with INDOT and the City of Scottsburg to develop the road diet concept and establish the project limits. US 31 was converted from four travel lanes (two lanes in each direction) to a three-lane section (one lane in each direction with a two-way left turn lane) from SR 56 to York Road (0.75 miles). The two-way left turn lane will allow motorists to make left hand turns without impacting traffic in the travel lanes of US 31, reducing the number of rear end collisions. US 31 was milled and resurfaced to remove all existing pavement markings and new thermoplastic pavement markings were installed to delineate the three-lane roadway section.
The construction cost of the project was $563,000.
