The challenge with the completed design of the project is the changing profile of the upper section of the pass which has been triggered by the recent hail storm. Large boulders came down the valleys and deposited on the existing track and washed down the Mkhomazana River. Some areas were undermined by the river due to the changing water course. Therefore, a 3m shift of the road alignment to the mountain side is required. Drainage structures at the upper section need to be redesigned to cater for boulder to wash through these structures. The project was delivered within desired time frames and currently in the Defects Liability period.

Approximately 25km from the pass lies the small town of Brandwacht. An equally picturesque landscape, the area has a population of roughly 2,000. But although the town is small, the road is busy with Garden Route tourists, trucks, and speeding traffic, making it a dangerous road for residents and schoolchildren to cross. In addition, the vertical and horizontal alignments of the road affect forward visibility and stopping sight distance, which means crossing it is a life-threatening hazard for pedestrians, especially when there is heavy rain and mist. At least five people, including four children, have died, and many others have been injured crossing the R328 at Brandwacht. On 4 April 2018, the Mossel Bay Municipality appointed Royal HaskoningDHV for the design, procurement, and construction supervision of the Brandwacht Pedestrian Bridge.

The P577 is a 4-lane dual carriageway provincial main road with at grade signalised intersections. It crosses the Mgeni river with the 410 m long Mgeni Viaduct. The viaduct is believed to be the steepest  incrementally launched structure built in the country to date.

The bridge provides a safe access to mainly school children from the Model Kloof neighbourhood who had to cross a very busy road. This project finally included some very innovative features which are leading the way in terms of public safety.
