Fieldwork is underway to study Burnet Road and North Lamar Boulevard in North Austin as workers gather information to design improvements. Work began on Burnet in late July and on North Lamar in late June, according Sara Behunek, communications manager for the city’s Corridor Program Office. The information-gathering step is part of the Corridor Construction Program being funded by the 2016 Mobility Bond that is allocating $482 million for corridor studies and construction. During the fieldwork phase, workers are conducting topographic, boundary and tree surveys and the activities will continue through the summer, Behunek said. In the next couple of weeks, workers may also begin geotechnical borings that involve making 6- to 8-inch-wide holes to take samples of the pavement, soil and rocks, according to the city. The geotechnical borings will take about one to two months to complete. As a result of the borings, drivers may see intermittent daily lane closures on Burnet Road between Koenig Lane and MoPac. On North Lamar, closures will occur between US 183 and Howard Lane at I-35. More information about the work is available at www.austintexas.gov/CorridorFAQ.
