Traffic arrangements at Bowen Place near the Kings Avenue bridge in Barton will change from 3:30pm on Wednesday as part of the ongoing construction of a new pedestrian and cycle crossing.
The off-ramp connecting Kings Avenue to the westbound carriageway of Bowen Drive will remain closed.
A partial closure of Bowen Drive located between Kings Avenue and the National Gallery of Australia will also be in place.
Pedestrians and cyclists will need to detour around the works for the duration of the project, but temporary speed cushions and a median refuge will be installed to maintain safety around the key crossing point.
On-road cyclists should also detour around the works area and where practicable use the off-road shared path network.
Traffic in the area will be directed by detour signs.
During the closure, the westbound carriageway of Bowen Drive will be open to two-way traffic with eastbound vehicles directed to cross into the westbound carriageway for a short distance.
Southbound traffic on Kings Avenue exiting into the Parliamentary Zone after crossing Lake Burley Griffin should continue southwards and turn right at King George Terrace.

The closures will remain in place from Wednesday afternoon until the project is completed in mid-2015.
The changed traffic arrangements are to enable the construction of a new grade-separated pedestrian and cycle crossing at Bowen Place.
When complete, the Bowen Place crossing will allow motorists, pedestrians and cyclists simultaneous safe passage through the area at all times.
The crossing design includes a 300-metre path under the existing road at Bowen Place, connecting Kings Avenue to the Lake Burley Griffin foreshore path network.
Path widening and pedestrian lighting works have been undertaken from Bowen Place along the lake foreshore to the north-east of the National Gallery of Australia Sculpture Garden as part of the project.
