The Jones Branch Connector over I-495 project in Fairfax County, Va., is not much to look at in terms of size—but its importance to the area is immense. The booming population in the Tysons area needs improved infrastructure, and the Jones Branch Connector—when complete in November 2019—will provide an important new link to S.R. 123 over the Capital Beltway (I-495). The road is expected to carry more than 32,000 vehicles per day by 2040. Crews are getting ready for an interim milestone due on Dec. 12, when at least one full lane of traffic in each direction will be open. The existing Jones Branch Connector is still waitiing to be widened to accommodate four total lanes of traffic, a center median, two 5-ft-wide bike lanes and two 12-ft-wide sidewalks through the entire corridor. The new bridge over the I-495 Express Lanes is complete.

This past January, Autodesk, in cooperation with the Federal Aviation Administration (FAA), tested autonomous UAVs at Atlanta’s Hartsfield-Jackson Airport. The seven flights that comprised this proof-of-concept trial represented the first civilian UAV flights approved by the FAA for a Class B airspace.
The purpose of these flights was to aid in the mapping plans for two new parking garages, as well as a relocating a public transit station, both of which are part of a $6 billion program for expansion and general improvement of the airport property.
The UAVs, or drones, which were programmed and flown by 3D Robotics measured the project area much faster than traditional measuring methods and have aided project planners in pushing their process forward.
Autodesk and 3D Robotics is on hand at the 2017 ConExpo-Con/Agg (in the Gold Hall) to display and discuss the 3DR Sightscan System, which was used in the Atlanta airport trial.
Roads & Bridges spoke with Autodesk Strategic Project Executive Tristan Randall and 3D Robotics’s Jeremiah Johnson about the proof-of-concept trial and what makes the 3DR such a unique system.
“This system,” Randall said, “is fully autonomous, so it do not require an active operator. The drone is programmed and then it follows its programmed course, and merely needs monitoring. It runs off an iPad app, and gathers data over GPS. This was the first Class B restricted airspace trail allowed by the FAA, and it was accomplished in only half a day, as opposed to the significantly larger period of time traditional methods would have taken.”
“Since we focused on pre-construction areas,” said Johnson, “and since the area was pre-programmed, there was no disruption of airport operations and there were no required closures of lanes. We worked with Atkins, the civil engineering consultant, to make it happen.”
Now that the proof-of-concept has been successful, Autodesk and 3D Robotics plan to move forward with further applications of the system, and to ultimately devise a digital repository for high-megapixel imagery.

On Friday, Feb. 8, San Diego Association of Governments (SANDAG) crews closed La Jolla Village Drive to thru traffic at Genesee Avenue in the University City area to set 60-ft-long concrete girders, or beams, to construct the elevated guideway for the future Mid-Coast Trolley. Crews hoisted the 95-ton precast girders using a crane and set the girders on the columns that were built at the intersection. The girders were trucked from Riverside on special industrial trucks built to withstand extra-heavy loads. Over the next several days the concrete continued hardening and gaining strength. Last week, high-strength steel cables were installed and tensioned inside the beams, allowing support towers in the intersection to be removed and the intersection to be opened by the morning of Friday, Feb. 15. The Mid-Coast Trolley Project will extend Blue Line Trolley service from Old Town north to the University City community. Nine new stations will be constructed. Major construction work began in 2016, with service anticipated to begin in 2021.

East Chicago, Ind., is coated in industrialization, and those at the Cline Avenue Bridge construction site are just doing their part to fit in. Roads & Bridges magazine checked out the progress on the bridge, which when finished will carry two lanes of traffic in and out of East Chicago over railroad tracks and the Indiana Harbor Canal. A four-lane bridge previously served as a connector for over 30 years, but in 2008 it was demolished. When complete, the new Cline Avenue Bridge will be 6,236 ft long with 170- to 300-ft spans. The main span over the Indiana Harbor Canal will be about 316 ft. The project is supposed to be complete in 2020, and the bridge will be tolled and can be expanded in the future to accomodate growth.
