Trinity Health Emergency – Ann Arbor Hospital
5301 McAuley Dr
Ypsilanti, MI 48197
ER Phone: 734-712-3000

Use this embedded Google map for general routing only. The official campus map identifies Emergency Drive and the hospital entrance area; follow on-campus signs for Emergency when arriving for ER care.

Emergency Drive

The official Ann Arbor campus map labels an Emergency Drive and an Emergency area near the hospital campus. Follow campus signage when you arrive.

Hospital entrance

The campus map identifies the Hospital Entrance at 5301 McAuley Drive, with nearby Main Surgery Center, North & East Towers, Select Specialty Hospital, Market Cafe, and Farmers Market labels.

Public parking

The campus map shows multiple public parking areas around McAuley Drive, Elliott Drive, Clark Road, and Huron River Drive. ER parking signs may differ from routine visitor parking.

Bus routes

The official campus map notes bus routes including Route 3 and Route 67. For urgent symptoms, do not rely on public transit when emergency transport is safer.

ER entrance, emergency parking, campus construction, and arrival planning

Trinity Health says the Ann Arbor Emergency Department remains open 24/7 and fully operational during construction and renovations. Build in extra time for non-life-threatening arrival, but do not delay emergency care.

Arrival topic What to know Practical step
Emergency entrance Follow campus signs for Emergency and Emergency Drive. For unstable patients, ask for immediate help at arrival or call 911 before leaving home.
Hospital entrance Hospital Entrance is listed at 5301 McAuley Drive on the campus map. Use emergency entrance for ER care, not routine hospital navigation, unless signage directs otherwise.
Public parking The campus map shows several public parking areas. For ER drop-off, prioritize safe patient unloading and follow posted emergency parking rules.
Construction and renovations The ED is undergoing renovation/expansion work but is stated to remain fully operational 24/7. Expect possible routing changes and follow updated on-campus signage.
Wheelchair or mobility needs Hospitals can assist at entry, but urgent safety comes first. Call 911 for unstable patients. For stable patients, ask staff for help at the ER entrance.
Family member arrival ER visitor access can change based on patient condition, unit capacity, privacy, infection control, and security rules. Bring ID and be ready to provide patient name, date of birth, and relationship.

When to use the Trinity Health Ann Arbor ER

Emergency departments are for serious, potentially life-threatening, or rapidly worsening conditions. Critically ill patients are seen immediately, even when the posted wait-time estimate looks long.

Emergency symptom Why it matters Best action
Severe chest pain or difficulty breathing May indicate heart attack, pulmonary embolism, severe asthma, pneumonia, or another critical condition. Call 911 or use the nearest ER immediately.
Stroke signs Sudden numbness, weakness, vision loss, speech trouble, or facial droop needs time-sensitive care. Call 911 and note when symptoms started.
Seizure, convulsions, or loss of consciousness May require urgent neurologic, metabolic, cardiac, or trauma evaluation. Call 911, especially if first seizure, prolonged seizure, injury, pregnancy, or breathing concern.
Compound fracture or major trauma Open fractures, serious crashes, falls, crush injuries, or severe wounds can involve shock or internal injury. Call 911 or go to the Level I trauma center if safe.
Poisoning or overdose Treatment timing may affect outcome. Call 911 or Poison Control if directed; bring substance packaging when safe.
Severe abdominal pain Could involve appendicitis, bowel obstruction, bleeding, pregnancy-related issues, infection, or other serious causes. Use emergency care if pain is severe, worsening, with fever, fainting, pregnancy, vomiting, or bleeding.
Pregnancy-related emergency Bleeding, severe pain, high blood pressure symptoms, decreased fetal movement, or trauma can need urgent evaluation. Call 911 for severe symptoms or go to emergency care as instructed by your care team.
Suicidal or homicidal thoughts Immediate safety risk requires urgent mental health or emergency response. Call 911 if there is immediate danger. Use ER or psychiatric access for urgent assessment.
Do not self-triage severe symptoms online. Wait-time estimates, map listings, review sites, and portal tools are not a substitute for emergency medical evaluation.

Emergency Room vs urgent care vs virtual care

Trinity Health explains that urgent care may be better for immediate but non-life-threatening needs, while the emergency department is for life-threatening or serious conditions.

Use ER / call 911
Severe chest pain, serious breathing problems, stroke signs, compound fracture, seizures, loss of consciousness, severe head/neck/back injury, deep wounds, severe burns, poisoning, pregnancy-related emergency, severe abdominal pain, or suicidal/homicidal feelings.
Use urgent care
Sprains, strains, back pain, fever or flu, sore throat, cough, skin infections, urinary tract infection symptoms, mild to moderate allergic reactions, minor broken bones, vomiting/diarrhea/dehydration when not severe, and cuts that may need stitches.
Use virtual care
Selected common conditions such as allergies, bronchitis, common cold, flu symptoms, pink eye, sinus infection, upper respiratory illness, painful urination, or yeast infection when clinically appropriate.
Use primary care
Routine follow-up, medication refills, non-urgent symptoms, chronic condition management, preventive care, referrals, and after-ER follow-up appointments.
When unsure: If symptoms are severe, sudden, rapidly worsening, or feel dangerous, treat the situation as an emergency and call 911 or use the nearest ER.

Pediatric emergency and mental health access

The official ER page lists separate pediatric emergency and psychiatric access routes. Use 911 for immediate danger, severe symptoms, or unsafe transport.

Pediatric Emergency

Phone: 734-712-2786. Use this route for pediatric ER contact questions when calling is safe. For severe breathing trouble, blue lips, seizure, trauma, poisoning, or infant fever emergency signs, call 911.

Fever in newborn

Trinity Health’s emergency guidance lists fever in a newborn younger than 3 months old as an emergency department reason. Do not wait for a routine appointment.

Psychiatric Access Center

Phone: 734-712-2762. Use for mental health routing when appropriate. Use 911 if a person may harm themselves or others.

Bring support details

For pediatric or mental health visits, bring medication list, allergies, diagnoses, therapist/doctor names, guardian details, custody/legal paperwork if needed, and recent discharge papers.

ER wait time: how to read it safely

The official ER page links an hourly-updated wait-time estimate through MyChart. Trinity Health notes wait time cannot be guaranteed because it depends on patient needs at arrival, and critically ill patients are seen immediately.

Wait-time item Meaning Safe interpretation
Updated hourly The number is a changing estimate, not a promise. Use it for general planning only when symptoms are not life-threatening.
Cannot be guaranteed Arrival volume and patient severity can change quickly. Do not delay emergency care because a wait time looks long.
Critically ill patients first Triage prioritizes the sickest or most unstable patients. A less severe condition may wait longer than a severe condition arriving later.
Long wait-time prompt The page may suggest looking at other local emergency departments if wait time is long. Only compare options when the condition is stable enough and driving elsewhere is medically safe.
MyChart arrival notice The page says you can let the ER know you are on the way through MyChart. Use it only if it does not delay calling 911, leaving for the ER, or getting urgent help.

MyChart ER tools, “let us know you’re on your way,” and portal limits

Trinity Health MyChart can help with appointment details, test results, prescription renewal, messaging, eCheck-in, health summaries, billing, and patient education. For the ER, the official page also mentions letting the team know you are on the way.

After the ER visit: discharge, follow-up, results, prescriptions, and red flags

Emergency care often ends with follow-up instructions. Read the discharge paperwork before leaving and ask questions if anything is unclear.

Review the diagnosis and next steps. Ask what condition was treated, what was ruled out, what still needs follow-up, and when to return immediately.
Confirm medications. Ask which prescriptions were started, stopped, changed, or should not be mixed with current medications.
Schedule follow-up. Ask whether to follow up with primary care, a specialist, imaging, lab, surgery, cardiology, neurology, pediatrics, behavioral health, or another service.
Check MyChart later. Review available test results, after-visit summary, billing, and messages when they appear. Some results may release at different times.
Watch return precautions. Return or call 911 if symptoms worsen, new severe symptoms appear, breathing becomes difficult, pain becomes severe, mental status changes, or discharge warnings occur.

ER bills can include hospital facility charges, physician/provider charges, imaging, labs, pathology, ambulance, observation, or outside professional billing. Keep every statement and insurance explanation of benefits.
