The summer months are unofficially known as construction season in Ohio, and as the weather slowly grows colder, several major construction projects in Dublin are drawing to a close.
While varied in scope and location, the projects will ultimately affect the flow of traffic and motorists' commutes.
Interstate 270-State Route 33 interchange
Construction cost: $68 million
Spring 2015 marked the beginning of this interchange project, which was undertaken to improve safety and reduce congestion by eliminating weaving and merging at the interchange, according to the Ohio Department of Transportation's website.
Paving is finished on this project, and ramps and lanes are open, said ODOT District 6 spokeswoman Nancy Burton. Remaining work includes landscaping and signs. The project should conclude by the end of October, she said.
North High Street widening
Construction cost: Just over $4.8 million
Construction on this project, which widens High Street between North Street and Indian Run Drive, began at the end of January and is slated to finish in the beginning of November, said Paul Hammersmith, Dublin's director of engineering.
Widening North High became necessary because of the growth in Crawford Hoying's Bridge Park development nearby, he said.
The project scope also includes a new intersection at North High Street and Rock Cress Drive, north of the Dublin Branch of the Columbus Metropolitan Library, Hammersmith said.
Southbound traffic on North High Street is able to travel between North Street and Indian Run Drive.
Northbound and southbound North High Street traffic is able to turn west on North Street throughout a majority of the project.
While southbound traffic is maintained on North High Street, northbound traffic on that street will be maintained between Bridge and North streets.
Drivers traveling northbound on North High Street have to take a detour from Bridge Street to Riverside Drive.
To access North High Street businesses, the library and Indian Run Elementary School, drivers should use North High Street or Darby Street.
Avery-Brand roads roundabout
Construction cost: $1.5 million
With traffic increasing in the northwest portion of the city as a result of Dublin's growth, a roundabout provided a way to eradicate delays at what was previously a four-way stop intersection, Hammersmith said.
The city's website Oct. 6 outlined the following impacts to traffic:
• North of Brand Road, Avery Road will be closed in both directions for approximately 200 feet.
Detour signs will direct traffic to use Glick Road to Muirfield Drive back to Brand Road or Avery Road.
• South of Brand Road, Northbound Avery Road will remain closed.
Southbound Avery Road will open south of Brand Road except during paving operations.
• Brand Road remains open for east-west travel with one-lane, two-way traffic maintained by temporary traffic signals.
The project is slated for completion Oct. 13.
Mid-century neighborhood improvements
Construction cost: $3.94 million
This project, which also includes section 4 of Waterford Village, updates five different streets including Grandview Drive, Longview Drive, Marion Street, Franklin Street and Monsarrat Drive, Hammersmith said.
Work includes water line replacement, street widening, pavement reconstruction and improvements to curbs, gutters and storm sewers.
No lane closures were involved with the project, which began in the spring and is slated to finish in November, Hammersmith said.
Annual street maintenance
Construction cost: $4.2 million
This year's street maintenance program includes about 45 streets in 16 neighborhoods throughout Dublin, Hammersmith said.
Projects are primarily curb and gutter replacement and pavement replacement.
Work began in the spring, and is slated to finish Oct.17, he said.
One hundred-gigabyte fiber deployment
Construction cost: Just under $1 million
In exchange for 1.6 acres for the construction of a 400-plus space parking garage for the library and to support parking needs in Historic Dublin, the city has allowed the school district use of its Dublink fiber optic network.
The project is about 75 percent finished, and the city hopes to wrap work up this month, Hammersmith said.
As work has progressed, lanes have been closed intermittently, and traffic has been maintained with flaggers, Hammersmith said.
