הסניף פתוח עכשיו, אבל מחר בבוקר המעבר יהיה סגור.

In standard Hebrew, the verb to be is usually omitted in the present tense.

So instead of saying The branch is open now with a separate word for is, Hebrew simply says:

הסניף פתוח עכשיו
literally: the-branch open now

This is very normal. The same thing happens with many adjective or noun sentences in the present:

• הדלת סגורה = The door is closed
• הוא עייף = He is tired
• אני סטודנט = I am a student

But in the future and past, Hebrew usually does use forms of to be, which is why you get יהיה later in the sentence.

יהיה means will be.

It is the 3rd person masculine singular future form of the verb היה / להיות = to be.

In this sentence:

המעבר יהיה סגור
= the passage/crossing will be closed

Hebrew needs יהיה here because the sentence is talking about a future state, not a present one.

A few related forms:

• יהיה = he/it will be masculine singular
• תהיה = she/it will be feminine singular
• יהיו = they will be
• אהיה = I will be

Because המעבר is a masculine singular noun, יהיה is the correct form.

Yes, in some contexts, especially in everyday speech, announcements, or signage, Hebrew can sometimes use a present-tense-looking structure to talk about a scheduled future situation:

מחר בבוקר המעבר סגור

That can sound like Tomorrow morning the crossing is closed or will be closed.

However, יהיה סגור is more explicit and clearly marks the future:

מחר בבוקר המעבר יהיה סגור

So:

• המעבר סגור מחר בבוקר = possible, more compressed or announcement-like
• המעבר יהיה סגור מחר בבוקר = clearer standard future statement

For learners, יהיה סגור is the safer pattern to recognize and use.

בבוקר means in the morning or simply in the morning / morning in this time expression.

It is built from:

• ב־ = in / at
• הבוקר = the morning

When Hebrew attaches the preposition ב־ to a noun with ה־ (the), the ה usually disappears in the combined form.

So conceptually:

ב + הבוקר → בבוקר

You see two ב letters because:

1. the first ב is the preposition in/at
2. the second ב is the first letter of בוקר

So מחר בבוקר literally comes out as something like tomorrow in-the-morning, but in natural English it is just tomorrow morning.

Because they agree with the nouns they describe.

• הסניף is masculine singular
• המעבר is masculine singular

So the adjectives also appear in the masculine singular form:

• פתוח = open
• סגור = closed

If the noun were feminine singular, the adjectives would change:

• התחנה פתוחה = the station is open
• הדלת סגורה = the door is closed

If plural, they would change again:

• הסניפים פתוחים = the branches are open
• המעברים סגורים = the crossings/passages are closed

So this sentence is a good example of normal adjective agreement in Hebrew.

The prefix ה־ is the Hebrew definite article, meaning the.

So:

• סניף = branch
• הסניף = the branch

and:

• מעבר = passage / crossing / transition
• המעבר = the passage / the crossing

Hebrew attaches the directly to the beginning of the noun, instead of using a separate word like English does.

Also, when a noun is definite, any adjective describing it is understood as definite too:

• הסניף פתוח = the branch is open
• המעבר יהיה סגור = the crossing will be closed

מעבר is a noun that can mean several related things depending on context, such as:

• passage
• crossing
• access way
• transition

Its basic idea is something connected to passing or moving across/from one side to another. It comes from the root ע-ב-ר, which is connected to passing, crossing, moving through.

So in different contexts, המעבר could mean:

• a border crossing
• a pedestrian passage
• a hallway or access passage
• a transition point

The exact English word depends on the situation, but grammatically it behaves here just like any regular masculine singular noun.

Hebrew often places time expressions early in the sentence to set the scene first.

So:

אבל מחר בבוקר המעבר יהיה סגור

feels very natural, because it first tells you when, and then tells you what will happen.

This is similar to English patterns like:

• But tomorrow morning, the crossing will be closed

You could move things around in Hebrew, for example:

• אבל המעבר יהיה סגור מחר בבוקר

This is also correct. The difference is mostly one of focus and style, not basic meaning.

Putting מחר בבוקר near the beginning is very common and natural.

A simple learner-friendly transliteration is:

ha-snif patuach akhshav, aval machar ba-boker ha-ma'avar yihye sagur

A slightly more careful pronunciation guide:

• הסניף = ha-SNIF
• פתוח = pa-TOO-akh
• עכשיו = akh-SHAV
• אבל = a-VAL
• מחר = ma-KHAR
• בבוקר = ba-BO-ker
• המעבר = ha-ma-a-VAR
• יהיה = yih-YE
• סגור = sa-GOOR

Two sounds that may feel unfamiliar to English speakers:

• ח in פתוח, מחר is a throaty sound, like the ch in German Bach or Scottish loch
• ע in עכשיו, המעבר is often very weak or silent in modern Israeli Hebrew, but historically it is a consonant

אבל means but.

It connects the two clauses and shows a contrast:

• הסניף פתוח עכשיו = the branch is open now
• אבל מחר בבוקר המעבר יהיה סגור = but tomorrow morning the crossing/passage will be closed

So the sentence is contrasting the current situation with a different future situation.

This kind of contrast word is very common:

• אבל = but
• ו־ = and
• או = or
• כי = because / that

Here, אבל helps the sentence sound natural and clearly oppositional: open now, closed later.
