South Lawn Project Update: Terrace Construction over JPA

Work on a distinctive feature of the South Lawn Project, the terrace crossing Jefferson Park Avenue, is expected to begin on Saturday, September 13.

The initial work in erecting the structural steel terrace foundation will include placing 13 support beams over the road – work that will take two days, Saturday and Sunday. To minimize the effect on traffic, the work will be conducted at night, beginning at 3 a.m. and continuing until 7 – 9 a.m. on each of the two days. Lights will be mounted on both sides of JPA to facilitate the work.

During the two-day construction period, traffic on JPA will flow normally until a beam is rigged and ready to be lifted into place over the road. At that time, all traffic will be stopped in each direction for approximately seven minutes while a beam is lifted into place and secured to steel girders on each side of the road. Once each beam is secured, traffic flow will return to normal. (To view the traffic plan, visit www.virginia.edu/communityrelations and click on the South Lawn Construction Update site.)

After the steel support beams have been installed, a variety of terrace work will continue over the next nine months. Initial work includes the placement of formwork and concrete on top of the steel beams and placement of precast concrete side panels on the east and wide sides of the terrace.

The bulk of such work will be conducted at night with the walking and driving area beneath the terrace protected from falling objects. Between 6 a.m. to 9 p.m., the normal two lanes of traffic flow on JPA will be maintained; between 10 p.m. to 5 a.m., traffic flow on JPA will be restricted to one lane with flag personnel on site to direct motorists.

Terrace work is subject to schedule changes due to weather conditions. If inclement weather causes cancellation of the structural steel work expected to occur this weekend, another project update will be distributed promptly.
