Narrative:

We were assigned 21R for departure. West ground gave us instruction to taxi 'kilo; taxi lane E4; short of foxtrot call ground 119.45.' I am 99.5 percent sure I complied with the clearance; technically. I am 100 percent sure I complied with the intent; as there was no correction given by ATC; traffic conflict; or any other issue. The technical compliance doubt arises from two items.1) taxi lane E4 is a temporary taxi lane; found only on the jepp construction diagram 10-8. Not only did it take us a while to locate it on the numerous available dtw taxi charts; but when we did; it confused us greatly because the chart is a limited chart in terms of the overall airport layout; oriented in a 'west up' manner. It seems minor; except when you are trying to get things done in the heat of the moment; a 'north' orientation arrow would have helped tremendously.2) the taxiway signage/ground markings in this area are horrendous. Like I said; I am fairly confident I held short of foxtrot as directed; but if there is definitive signage as to where foxtrot begins; we both could not locate it.suggestions:1) orient taxi charts north up; always.2) improve signage in temporary areas.3) temporary taxi lanes should be referenced on all taxi diagrams; and/or more obvious/easier to identify. They took the time to plan the taxiway; it could certainly be more evident in the jepp.

Original NASA ASRS Text

Title: Air carrier Captain reported the DTW 10-8 airport chart is in a west up orientation and is very confusing. The data is dense and relating the 10-8 notes to the 10-9 is difficult. Finding the equivalent 10-9 location in a north up orientation versus the 10-8 west up alignment is mentally difficult.
