Work on East Hanna Ave. & Central Ave. Traffic Update

David Nelson Construction has re-arranged its construction schedule to focus on Central Avenue south of Hillsborough, Crest Avenue and the Hillsborough River outfall. The revised schedule means crews will be working on East Hanna Avenue near Seminole Heights Elementary School in spring of 2023 instead of 2022.

This change will not affect the overall schedule, but it will help the project team reduce impacts to the neighborhoods where crews are currently working, particularly near Hillsborough High School. Construction on Central Avenue is exacerbating traffic congestion near the high school which is impeding residents’ access to homes. This schedule change will help us complete work on Central before the start of the next school year, barring unforeseen conditions.

We are working with Hillsborough High and the school district on options for reducing traffic tie-ups during school drop-off and pick-up. Additionally, the contractor is working to improve traffic on Central between Louisana and Wilder to ease congestion. However, construction activity will increase on Central in coming months. If you are a parent or guardian of a student at HHS who routinely drops off or picks up a student, you must follow the rules regarding traffic flow and be as efficient as possible to avoid blocking in neighborhood residents.

Work on Tunnel Under I-275 Begins in Late January

Work will begin on or about Jan. 24, 2022, to install a stormwater pipe under I-275 from North Taliaferro Avenue west to Caracas Street. This work continues through April, barring unforeseen conditions.  The pipeline will be installed under I-275 by microtunnel, a trenchless construction technique that involves:

  • Installing dewatering wells and pumps that will run 24 hours a day continuously through the duration of the work.
  • Digging large tunnel shafts on both sides of the interstate (at the Taliaferro/Caracas intersection and at the end of East Caracas Street on the west side of I-275).
  • Staging a soil separating machine, control trailer and other equipment on Taliaferro.
  • Bringing a crane into the areas to lower the tunnel boring machine into the sending shaft, to lower pipe into the shaft through the tunneling operation, and to retrieve remove the tunnel boring machine, once complete.
  • Crews will work from 7 a.m. to 7 p.m. Monday through Saturday until tunneling is complete.

Crews will install the 72-inch diameter stormwater pipeline on Caracas as the tunnel operation is completed. Residents should expect to hear construction noise and possibly feel some vibration during tunneling and pipeline installation.

Microtunnel work area East Caracas and Taliaferro

North Taliaferro Avenue will be closed from East Wilder Avenue to East Ellicott Street as crews install a stormwater pipeline under I-275.


POSTPONED: Central Avenue Closure North of Hillsborough Avenue

CORRECTION: Minimal Construction to Occur Over Holidays

Previously we shared that there would be no construction over the holidays. However, there will be minimal activity during this timeframe.

Dewatering pumps must continue to run to dry the soil for construction, and one crew will be installing a water main on Dec. 24 and Dec. 27-31, 2021.

We apologize for the inconvenience. We wish you and your family a happy and healthy holiday season, and we thank you for your patience as we improve infrastructure in your area.

Northbound Central Remains Closed

Due to slower than anticipated progress, northbound Central Avenue remains closed to traffic. We hope to open the northbound lane of Central from Osborne to Wilder the week of December 20, and leave it open through January 2022. We also are trying to work with the school district on solutions to the traffic backups we know many of you are experiencing when traveling down Central at school drop-off or pick-up times.

Construction on Ellicott Street begins Monday, Dec. 13

Beginning Monday, Dec. 13, 2021, construction crews will be working on Ellicott Street from Central Avenue to I-275 to install a water main.

No construction work will take place Dec. 24, 2021, through Jan. 2, 2022. Construction will resume on Monday, Jan. 3, 2022. We wish you and your family a happy and healthy holiday season and thank you for your patience as we continue to move forward with this important infrastructure project.

Northbound Central Reopened to Wilder Avenue

As soon as Monday, Dec. 6, the northbound lane on Central Avenue will be reopened to traffic from Osborne to Wilder Ave. Motorists may then turn left on Wilder to exit the Old Seminole Heights neighborhood via Florida Avenue. Northbound Central is expected to remain open to Wilder until late January or early February 2022, before being closed again for the installation of a 72-inch stormwater pipe.

Central Avenue open from Osborne to Wilder

Construction Update for Central and West Crest Avenues; Thanksgiving Work Schedule

Crews will begin excavation work on West Crest Avenue at North River Boulevard today or tomorrow. Work is anticipated to progress eastward on West Crest Avenue next week.

In preparation for water main relocation on Caracas Street, the northbound lane on Central Avenue will be closed at Caracas beginning today. Vehicles will no longer be able to travel north on Central to Wilder Avenue.

No construction work will take place from Nov. 25 through Nov. 28, 2021, as David Nelson Construction and its employees celebrate Thanksgiving with their families and friends. Full construction will resume Monday, Nov. 29, 2021.

We wish you all a happy Thanksgiving and thank you for your support of this important infrastructure project.

Construction on Caracas Street on Monday, Nov. 22

Beginning Monday, Nov. 22, 2021, construction crews will be working on Caracas Street from Central Avenue to I-275. They are relocating a water main in preparation for excavating a micro-tunnel shaft under the Interstate beginning in December.

Northbound Central from Osborne to Hillsborough Closed Through August 2022

Beginning Monday, Nov. 1, 2021, northbound Central Avenue will be closed from Osborne to Hillsborough avenues. Central Avenue will be southbound only between Hillsborough and Osborne avenues until August 2022 as crews relocate a water main, install a new 72-inch stormwater pipe and box culvert, and make transportation improvements on Central Avenue.

Northbound traffic on Central Avenue will be detoured at East Osborne Avenue to Florida Avenue and Nebraska Avenue.
