How St Andrew St, part of State Highway 88, might be better presented was one thing studied by Jasmax.
Reducing the part between Cumberland and Castle Sts from four lanes to two could allow for wider footpaths and two rows of garden beds and trees, illustrations show.
Having three lanes of traffic instead could be complemented by greenery on one side of the street.
Space for amenity might enable significant improvements to the quality of the pedestrian environment, Jasmax said in a report for Waka Kotahi NZ Transport Agency and the Dunedin City Council.
Widened footpaths would also provide better access between the new hospital and the bus hub, and seating and separation from moving traffic would improve the quality of the pedestrian experience, the firm said.
St Andrew St is between the planned inpatient and outpatient buildings of the new hospital.
It is expected the hospital will result in many more pedestrians and cyclists using the area.
As things stand, St Andrew St is also part of the main east-west link into and out of the central business district.
That creates a conflict and it has been suggested a high-volume vehicle flow through there should not be allowed to continue in the years ahead.
Where the street meets the northbound one-way Cumberland St, SH 1, is where SH 88 ends, but the termination point for SH 88 appears likely to shift a little north.
Civil engineering firm WSP has looked into both the possibility of a different end point for SH 88 and how changes to St Andrew St might affect the network.
It studied three options relating to the part between Cumberland and Castle Sts.
A two-lane concept for this part of St Andrew St would not feature right turns out of it.
Of the two three-lane options, one would allow right turns into both Cumberland and Castle Sts.
The other would ban turning right into Cumberland St.
The transport agency has said modelling showed fewer traffic lanes in St Andrew St and banning right turns might have little impact on the performance of the network.
"Removing turning movements would free up more space for people-friendly spaces and pedestrian crossings."
