Project Overview x

The intersection of Johns Road and Klatt Road in south Anchorage was challenging due to high traffic volume. This traffic came from the nearby elementary school, local concrete and aggregate supplier, and neighborhood residences. Before construction, the intersection had a two-way stop condition, making it hard to turn left from and onto Johns Road during peak traffic hours. Furthermore, the intersection’s location at the top of a hill made it tough for drivers to see oncoming traffic, which posed a safety risk.

To solve these issues, the Highway Safety Improvement Program (HSIP) project constructed a single-lane roundabout. This improved pedestrian access and provided better sight distance at the intersection.

In addition to the roundabout, the project included widening Bragaw Street. This was necessary because of an increase in left turns from the 4-lane Bragaw Street to access adjacent businesses and residential neighborhoods. A two-way center left-turn lane with median barriers was added as a solution.

HDL’s construction administration (CA) team managed the day-to-day construction activities. The team provided construction inspection, prepared progress payments, performed SWPPP inspection, conducted and prepared minutes for progress meetings, and maintained project files and records.

Although it was a smaller roadway project, it had complex elements that required HDL’s team to pay great attention to detail. Multiple utility contractors, the prime contractor, DOT&PF, the Municipality of Anchorage, and the public needed to coordinate for the project’s success. To complete the project on time and with minimal change orders, HDL’s team put in a lot of effort and hard work. Fortunately, the team’s dedication paid off, and the project was successfully completed, improving traffic flow safety and efficiency in the surrounding community. Ultimately, the project was finished on time and with minimal change orders.
