I-91 is the major north–south transportation corridor for the center of the state. It is the main route between the larger cities of New Haven, Hartford, and [[Springfield, Massachusetts]]. As such, it is almost always heavily trafficked (especially during rush hour) and maintains at least three lanes in each direction through Connecticut except for a short portion in Hartford at the interchange with [[Interstate 84 (Pennsylvania–Massachusetts)|I-84]], and another in [[Meriden, Connecticut|Meriden]] at the interchange with [[Connecticut Route 15|Route&nbsp;15]]. The three cities also serve as Connecticut's control points along its length of the Interstate.<ref>{{cite book |last1 = Boyle |first1 = Doe |title = Fun with the Family Connecticut: Hundreds of Ideas for Day Trips with the Kids |date = 2011 |publisher = Rowman & Littlefield |isbn = 978-0-7627-6879-0 |url = https://books.google.com/books?id=xic1huFa1ZEC&pg=PA144 |access-date = August 10, 2018 |via = [[Google Books]] |language = en |archive-date = January 14, 2023 |archive-url = https://web.archive.org/web/20230114200616/https://books.google.com/books?id=xic1huFa1ZEC&pg=PA144 |url-status = live }}</ref><ref name="impact">{{cite book |author = Bureau of Planning and Research |title = I-91 Reconstruction from Hartford to Enfield; I-291 Construction from Windsor to Manchester: Environmental Impact Statement |date = August 1984 |url = https://books.google.com/books?id=Lbs1AQAAMAAJ&pg=PA49 |access-date = August 10, 2018 |via = Google Books |language = en |page = 49 |location = [Wethersfield, CT] |publisher = [Connecticut Department of Transportation] |oclc = 53099516 |archive-date = January 14, 2023 |archive-url = https://web.archive.org/web/20230114200613/https://books.google.com/books?id=Lbs1AQAAMAAJ&pg=PA49 |url-status = live }}</ref>

I-91 begins just east of [[Downtown New Haven]] at an interchange with [[Interstate 95|I-95]] ([[Connecticut Turnpike]]). At the bottom of the ramp for exit&nbsp;5, [[U.S. Route 5|US&nbsp;5]] begins at the first of its many interchanges with the freeway.<ref name="log" /> Leaving New Haven, I-91 follows a northeastward trek into [[North Haven, Connecticut|North Haven]], where it meets the southern end of the [[Connecticut Route 40|Route&nbsp;40]] expressway.<ref>{{cite web |author = Connecticut Department of Transportation |title = ConnDOT: Nighttime Installation of Rumble Strips on Route 40 in North Haven and Hamden and I-91 in Wallingford |url = http://www.ct.gov/dot/cwp/view.asp?a=2135&Q=586840 |publisher = Connecticut Department of Transportation |access-date = August 10, 2018 |language = en-us |archive-date = August 10, 2018 |archive-url = https://web.archive.org/web/20180810174602/http://www.ct.gov/dot/cwp/view.asp?a=2135&Q=586840 |url-status = live }}</ref> It travels through the eastern part of [[Wallingford, Connecticut|Wallingford]] before entering the eastern part of the city of [[Meriden, Connecticut|Meriden]].

It then enters [[Hartford County, Connecticut|Hartford County]] in the town of [[Rocky Hill, Connecticut|Rocky Hill]] and then enters Wethersfield, meeting the [[Connecticut Route 3|Route&nbsp;3]] expressway, which leads to [[Glastonbury, Connecticut|Glastonbury]] and the [[Connecticut Route 2|Route&nbsp;2]] expressway via the [[William H. Putnam Memorial Bridge]] over the [[Connecticut River]]. From there to [[St. Johnsbury, Vermont]], I-91 parallels the river, never more than {{convert|5|mi|km|spell=in}} from its west bank.<ref>{{cite web |title = Interstate Route I-91 Corridor Planning Study |url = http://www.pvpc.org/sites/default/files/I91ExistingConditionsE1toE5July15.pdf |access-date = August 10, 2018 |website = pvpc.org |publisher = Pioneer Valley Planning Commission |archive-date = August 11, 2018 |archive-url = https://web.archive.org/web/20180811031813/http://www.pvpc.org/sites/default/files/I91ExistingConditionsE1toE5July15.pdf |url-status = live }}</ref> I-91 then enters the [[Hartford, Connecticut|Hartford]] city limits; in that city, it has a set of interchanges with US&nbsp;5/Route&nbsp;15 ([[Wilbur Cross Highway]]), which provides access from I-91 north to I-84 east, and from I-84 west to I-91 south via the [[Charter Oak Bridge]].<ref>{{cite web |author = Connecticut Department of Transportation |title = Department of Transportation Event Detail |url = http://www.ct.gov/dot/ical/eventDetail_page.asp?date_ID=C9C8CAC6C983CDC8CC |publisher = The State of Connecticut |access-date = August 10, 2018 |language = en-us |website = www.ct.gov |archive-date = August 11, 2018 |archive-url = https://web.archive.org/web/20180811031737/http://www.ct.gov/dot/ical/eventDetail_page.asp?date_ID=C9C8CAC6C983CDC8CC |url-status = live }}</ref> I-91 then has an interchange with I-84, where all other transitions to and from I-84 take place.

I-91 then enters [[Windsor, Connecticut|Windsor]] and meets the western end of its other Connecticut spur route, [[Interstate 291 (Connecticut)|I-291]]. At the Windsor–[[Windsor Locks, Connecticut|Windsor Locks]] town line, it meets the eastern terminus of the [[Connecticut Route 20|Route&nbsp;20]] expressway, which provides direct access to [[Bradley International Airport]].<ref name="impact" /> A couple of miles further north, I-91 crosses the Connecticut River on the [[Dexter Coffin Bridge]] into [[East Windsor, Connecticut|East Windsor]].
