Grosse Ile outlines April start, weight limits and escort rules for two-month toll-bridge period

Grosse Ile Township officials told residents and business owners at a public meeting that the township expects a temporary shift to the privately operated toll bridge beginning about April 1 for roughly two months while a nearby free bridge is repaired.

The township supervisor said: "Approximately April 1 will be the start time. It'll be approximately 2 months," and described operational limits set after an engineering review. The supervisor added that the private owner of the toll bridge "can put any weight limit he wants on that bridge," and that township engineers recommended new operational thresholds to reduce the risk of damage while the township prepares upgrades.

Why this matters: The closure of the free bridge will route local and commercial traffic — including deliveries and construction-related vehicles — onto the toll bridge, which serves roughly 11,000 island residents. Officials said the temporary limits and escort rules are intended to keep the bridge operable for residents while the township and county complete repairs and longer-term upgrades.

Key details

- Timing: Officials said the purchase closing on the toll bridge is scheduled for March 31 and the temporary operational plan is expected to begin about April 1 and last about two months.

- Weight limits and escorts: Township staff said two-way, unescorted traffic will be limited to 24,000 pounds (about 12 tons) so two opposing vehicles can pass safely. For heavier loads, staff said vehicles between 24,001 and about 48,000 pounds should bring a trip ticket showing a certified weight and coordinate in advance for an escorted crossing. Derek, a township staff member, summarized the protocol: "24,001 pounds to 48,000 pounds, bring a trip ticket, don't come during rush hour."

- Blackout hours for escorted crossings: Officials identified morning and afternoon peak periods when escorted overweight crossings will not be permitted because of expected backups. The township stated those periods as roughly 6 a.m. to 9 a.m. and 3 p.m. to 7 p.m.

- Examples and contractor guidance: Speakers and contractors at the meeting discussed concrete mixers and gravel trains as typical problem loads. Attendees said common concrete mixers can weigh about 37,000 pounds empty and a fully loaded concrete truck can reach roughly 66,000–70,000 pounds; meeting participants concluded that partial loads (roughly 5 cubic yards) are more likely to be allowed than full loads. Officials asked businesses to obtain weight information from vendors and carriers so crossings can be coordinated.

- Toll and passes: The township said the current toll rate structure in place at the bridge will remain in effect during this period; residential bridge-pass programs will remain valid. Township officials said they do not yet know whether the toll operator’s systems are set up for commercial billing accounts and that they will follow up on whether commercial passes or billed accounts are available. The supervisor said the township will post the current pay schedule on its website.

- Staffing and operations: Officials said bridge workers who already operate the toll bridge will remain on for at least 90 days after township ownership and that the township plans to increase staffing at the toll booths to try to move traffic more quickly. They also said the township will post a bridge number for businesses to call to report overweight vehicles arriving (township guidance requested roughly a half-hour notice so escorts can be prepared).

- Revenue and review: Officials said the township modeled anticipated bridge revenue and the millage voters approved to sustain initial operations. The supervisor and staff said they plan to leave toll rates unchanged for the first year to match the revenue model and to reassess rates and commercial billing after operating experience is gathered.

- County coordination and future closures: Township leaders said Wayne County is coordinating its own repairs to the free bridge and that a larger, longer closure could occur in the future (officials described a potential second closure a couple of years out). The township said it wants to complete upgrades so the toll bridge can accept heavier truck traffic before any larger county project proceeds.

What residents and businesses were told to do

- Businesses and contractors: get certified vehicle weights from vendors and carriers, schedule deliveries for non-peak hours when possible and contact the bridge operations number (to be posted on the township website) about planned overweight loads.

- Drivers: expect to pay the toll when returning to the island (the township said it will allow vehicles to depart the island without paying and collect once they return), bring trip tickets for loads between 24,001 and 48,000 pounds, and be prepared for possible waits if an escorted crossing is required.

Concerns raised at the meeting

Small-business owners repeatedly urged the township to review toll rates for commercial vehicles; officials said they understand the economic concerns and will re-evaluate rates after at least a year of operation. Several speakers asked how deliveries delayed en route would be handled; township staff said those situations would be decided case-by-case at the bridge operator’s discretion and that staff would follow up with the bridge operations manager, Maureen, for more specific guidance.

Next steps and where to get information

Officials said they will publish the current toll schedule and operational guidance on the township website, will provide a bridge operations phone number for coordination of overweight vehicles and that staff will contact businesses that raised specific operational questions. The township emphasized that the April start and two-month duration are the current plan and that residents and businesses will be notified promptly of any changes.
