Preparatory work was already carried out last year and the median crossings were set up. Starting March 17, 2025, the main construction measure will begin heading north. Heading south, the emergency lane will be used as an additional lane and traffic will be shifted to the right. This creates an additional lane that will be used for oncoming traffic - a so-called trough lane.

Color Guidance Concept to Ease Lane Choice During Southeast Tangent Renovation

A color guidance system is intended to make orientation easier: For example, those who want to exit at Handelskai must keep to the right, while the trough lane can be used for all other directions, according to Asfinag Regional Manager Brigitte Müllneritsch. The construction site heading north will proceed in three phases. In the first construction phase, which lasts ten weeks, the construction site is located on the far right. Then it "moves" to the middle for two weeks: During this traffic phase, the Handelskai exit is closed for vehicles coming from the A23 and driving on the three left lanes. In the last phase, the construction site is located on the far left for one week. The three lanes on this side will then pass the construction site on the right.

Completion of Southeast Tangent Renovation in August 2026

During the construction, the so-called bypass ramp in the direction of Handelskai at the Prater junction will be closed - but the exit towards the city center will remain open. After the work is completed, the construction site will be processed from June 23 heading south in the same sequence. After a winter break from October 2025 to March 2026, the two junctions Prater and Handelskai will be renovated starting March 2026. The measures are expected to be completed by the end of August 2026.
