The tender for the $13.5 million Main Street South reconstruction project has finally been issued.
The province called for proposals for work on PTH 5A, the main access into the City of Dauphin from the south, as a result of expanded commercial development along the route which has brought with it increased traffic volumes and higher collision rates.
The 1.7-km project covers a section of PTH 5A from Whitmore Ave., south to Triangle Road, and includes surface reconstruction with the creation of a divided highway.
The plans call to improve safety in the commercial area by having all local accesses connect to service roads, and service roads connecting to PTH 5A at upgraded intersections. Those service roads will be constructed along both the east and west sides of highway from their existing points south to Triangle Road.
As well, a new intersection allowing access to Dauphin Market Place Mall will be developed, complete with traffic signals.
Improvements and restorations to the road will benefit the community and the region by enhancing safety and traffic flows along the high-volume, main thoroughfare that is an integral trade route to economic development in the area.
Included in the project is a new drainage system design for the south end. The plan includes the digging of two retention ponds, one on each side of the highway, which will collect spring runoff, as well as runoff from major weather events.
“They’re slow releases. So the intent is that they actually run dry in the summer months, or during drier times, but be able to fill up again in a big event,” said Mike VanAlstyne, director of Public Works and Operations, adding the installation of 830 metres of storm sewer pipe below ground is also included in the drainage plan.
“It’s a big project that’s very complicated, but it’s not really. It’s moving water from one place to another, where it wants to go. But just moving it on your timeline not nature’s.”
The cost of the drainage system has been pegged at $8.15 million which the city will debenture through the province.
The original plan called for a project extending over two construction seasons with the bulk of the construction work taking place in year one and the finishing touches being added early in the second year. That is obviously no longer the case, VanAlstyne said.
“The hope is that it would (start) this fall, or say late summer if it’s September. Construction would end next August,” VanAlstyne said, adding while the project was originally slated to begin this spring, the delay is not as bad as it might seem. “Not terrible. There’s a pretty aggressive work schedule tied to it.”
The issuing of the tender also clears the way for another long-awaited project as earth excavated to construct the retention ponds, or a portion of it anyway, will be used to construct the toboggan hill at Maamawi Park, VanAlstyne said.
“Approximately 25 per cent of the excavation material is going (to the development on the Dauphin Recreation Services grounds), the remainder is going elsewhere,” VanAlstyne said, adding the drainage project is going to produce about 30,000 cubic meters of excavation material. “These are big retention ponds.”
