Match name of route between interections

/(([^&]+)\s&\s+([^,]+),\s([^,]+),\s([a-z]+)\s(\d+))\s-\s(([^&]+)\s&\s+([^,]+),\s([^,]+),\s([a-z]+)\s(\d+))/i

Broadway Ave & Broadway, Everett, Washington 98201 - Walnut St & 19th St, Everett, Washington 98201

/(([^&]+)\s&\s+([^,]+),\s([^,]+),\s([a-z]+)\s(\d+))\s-\s(([^&]+)\s&\s+([^,]+),\s([^,]+),\s\5\s(\d+))/i

Both points have same state and ZIP

/(([^&]+)\s&\s+([^,]+),\s([^,]+),\s([a-z]+)\s(\d+))\s-\s(([^&]+)\s&\s+([^,]+),\s([^,]+),\s\5\s\6)/i

Same city, state, and ZIP

/(([^&]+)\s&\s+([^,]+),\s([^,]+),\s([a-z]+)\s(\d+))\s-\s(([^&]+)\s&\s+([^,]+),\s\4,\s\5\s\6)/i

Route between intersections: Street and cross streets (same city, state, and ZIP)

/(?:([^&]+)\s&\s+([^,]+),\s([^,]+),\s([a-z]+)\s(\d+))\s-\s(?:(?:([^&]+)\s&\s+\1,\s\3,\s\4\s\5)|(?:\1\s&\s+([^,]+),\s\3,\s\4\s\5)|(?:([^&]+)\s&\s+\2,\s\3,\s\4\s\5)|(?:\2\s&\s+([^,]+),\s\3,\s\4\s\5))/i

Commented XRegExp version (for clarity)

(?:

	\s&\s+
	(?<street2>[^,]+) #street2
	,\s
	(?<city>[^,]+) #city
	,\s

	\s+
	(?<zip>\d+) #zip
)
\s-\s # Separator between intersections
(?:
	(?:([^&]+)(?#other cross street)\s&\s+${street1},\s${city},\s${state}\s+${zip}) 
	# capture 6 is the other cross street - if not undefined then street1 is the main street
	|
	(?:${street1}\s&\s+([^,]+)(?#other cross street),\s${city},\s${state}\s+${zip})

	# capture 8 is the other cross street - if not undefined then street2 is the main street
	|
	(?:${street2}\s&\s+([^,]+)(?#other cross street),\s${city},\s${state}\s+${zip}) 
	# capture 9 is the other cross street - if not undefined then street2 is the main street
)
