I-81 Syracuse Project Update: Open House Set on I-690 Detour, Drainage Work

I-81 Syracuse project update: the New York State Department of Transportation will hold a public open house on November 5 to preview the next construction stage of the I-81 Viaduct Project, including a two year eastbound I-690 detour expected to begin in late 2027 and a new stormwater trunkline under downtown Syracuse (WSYR NewsChannel 9; FingerLakes1.com).

The open house is the first look the public will get at how the two newest contracts will be built. Contract 6, the $2.1 billion I-690 reconstruction, is the largest contract in NYSDOT history, and Contract 6a, a $143 million drainage package, was awarded in September (WSYR NewsChannel 9; Equipment World). WCG covered the overall program at the start of the year (Syracuse I-81 Viaduct: NY’s $2.25B Largest Road Construction Project). This post focuses on the newly announced public meeting and the detour and drainage details released with it.

What Happened

NYSDOT confirmed the open house for Thursday, November 5, from 6 to 8 p.m. at Palladian Hall in The Treasury, 101 South Salina Street (FingerLakes1.com; WSYR NewsChannel 9). There will be no formal presentation. State staff and the prime contractors will answer questions next to renderings and videos, and information on air quality and vibration monitoring will be available (FingerLakes1.com). WSYR reported that this is the first in a series of open discussions on the project (WSYR NewsChannel 9).

The Two Contracts

Contract 6: I-690 reconstruction

WSYR reported that Contract 6 was awarded June 30 to CNY Alliance Six for $2.1 billion, covering the rebuild of I-690 and its separation from I-81, with removal of the I-81 viaduct itself coming in a later phase (WSYR NewsChannel 9). Equipment World reported that the award is the highest value contract in NYSDOT history (Equipment World).

According to FingerLakes1.com, the contract rebuilds and realigns I-690 in both directions between Leavenworth Avenue and North Crouse Avenue, builds new Business Loop 81 connections to I-690, completes an interchange at North Crouse and Irving avenues, and creates a street level intersection at West and West Genesee streets (FingerLakes1.com). Work on 25 local streets will add or replace sewer and water lines, lighting, sidewalks, shared use paths and trees (FingerLakes1.com; Equipment World).

Contract 6a: downtown stormwater trunkline

Contract 6a was awarded September 3 to Lancaster Development and Tully Construction Company for $143 million (WSYR NewsChannel 9). It covers an 8 foot by 10 foot concrete stormwater trunkline beneath Almond Street, East Water Street, State Street, Erie Boulevard, Salina Street and Herald Place (FingerLakes1.com). The line is meant to separate stormwater from sewage, reduce highway flooding and limit combined sewer overflows into Onondaga Creek and Onondaga Lake, and five streets on the route will be rebuilt with new signals, lighting, pavement markings, trees and better pedestrian and bicycle space (FingerLakes1.com). A DOT spokesperson told WSYR the start date for that work is not yet certain (WSYR NewsChannel 9).

The I-690 Detour

The biggest change for drivers is still about a year away. Eastbound I-690 is expected to close for about two years starting in late 2027, sending traffic from the near Westside and the western and northern suburbs onto city streets (FingerLakes1.com; WSYR NewsChannel 9). WSYR described the planned route as Genesee Street to James Street, a short right onto Oswego Boulevard, then Erie Boulevard East and Canal Street (WSYR NewsChannel 9).

I-81 Syracuse Project Update: Where Things Stand

Phase 1 of the I-81 program began in spring 2023 and focused on work tied to redesignating I-481 as I-81, including rebuilding the northern and southern I-481 and I-81 interchanges and early steps toward Business Loop 81 (Equipment World). Contract 6 and Contract 6a move the program into downtown Syracuse, where the work overlaps city utilities, local streets and the I-690 corridor (FingerLakes1.com).

Implications for Owners, Developers, Contractors and Subs

• Subcontract volume is coming. Two prime awards totaling more than $2.2 billion cover highway, bridge, utility, drainage, lighting and streetscape scope, which means years of work for regional subcontractors and suppliers (WSYR NewsChannel 9).
• Downtown logistics will get harder. Owners and builders with projects near Almond Street, Erie Boulevard, Salina Street and the I-690 corridor should plan deliveries, crane picks and staging around the drainage work and the late 2027 detour (FingerLakes1.com).
• Monitoring matters. NYSDOT is providing air quality and vibration monitoring information, a sign that nearby building owners will want baseline condition surveys before heavy work starts next door (FingerLakes1.com).
• Utility coordination is part of the job. New sewer, water and stormwater lines on 25 streets plus the trunkline route will affect service connections for adjacent properties (FingerLakes1.com).

What to Watch

• The construction start date for Contract 6a, which NYSDOT has not set (WSYR NewsChannel 9).
• Further open houses in the series and any updated detour maps (WSYR NewsChannel 9).
• The late 2027 start of the eastbound I-690 closure (FingerLakes1.com).

Bottom Line

The I-81 Syracuse project is moving into its most disruptive downtown stage. NYSDOT will explain the $2.1 billion I-690 rebuild, the $143 million stormwater trunkline and the planned two year eastbound I-690 detour at a November 5 open house, giving contractors, property owners and commuters their first detailed look at what is coming (WSYR NewsChannel 9; FingerLakes1.com).
